Terraforming Mars: Hellas Elysium - The Other Side of Mars Expansion by Stronghold Games, Strategy Board Game

Terraforming Mars (TM) is absolutely fantastic. I'd give it 6 stars if I could. It's that good. Definitely a gamer's game (ie. not intended for newcomers/nongamers), but worth every penny. With that said, TM has a bit of a learning curve.TM also has a wonderful solo variant, so if you're looking for a challenge, and you like to play solo (or at least have that option), look no further. That's actually the main reason I bought this game, and yet now I can't wait to try it multiplayer. And since it has the solo mode, I'll be able to teach it no problem and help move the game along as well. Another huge plus for me.At its core, TM is an engine builder, with cards and projects to help increase 6 main resources and production of said resources (MegaCredits=money, Steel, Titanium, Plants, Energy, and Heat). I won't go into great detail, but it's from these resources and a set amount of starting resources depending on which Corporation (think player) you play as that you start your engine building. There are 5 beginner corporations that are generic and all the same, and then there are an additional 12 that each have their own special ability(ies) and amount of starting credits, and possibly resources and/or resource production. I recommend starting with a beginner corporation, as knowing which cards to keep during setup also has a learning curve.Throughout the game, the player(s) are attempting to gain victory points (known as Terraform Rating, or TR) while simultaneously terraforming the planet. This terraforming includes 3 main elements: increasing temperature, oxygen levels, and water/ocean tiles.In the solo mode, you are attempting to complete all 3 of these before the end of your 14th turn. If you do so, you win. You can also keep track of your best scores, though TM isn't simply just a beat your own score solo mode. You actually have to WIN first (ie. complete the 3 elements to terraforming by end of turn 14), which is NOT easy. It's very clever, and very fun. Games typically take me 1-2 hours.In multi mode, you are trying to accrue the highest TR at the game end, signified by the completion of all 3 elements of terraforming. However, you score not only points from your base TR, cards, city tiles, and plant tiles (as in the solo mode), but also from any awards or milestones that you claimed. In that regard TM is somewhat of a point salad game...which I think is great. Again, looking forward to trying it multiplayer.While initially there is some luck of the draw, this is mitigated each turn during the refresh phase, as each player gets to look at 4 new cards from the deck and decide how many to keep, paying 3 credits per card. It is also and perhaps more so mitigated by the standard projects listed on the board, which every player has access to every turn regardless of which cards they may or may not have. These can be key in the solo mode if you don't get the best starting cards, which I assume would be true multiplayer.At a $41 price point, I can't recommend this game enough. It has numerous expansions (I think around 5 or 6), so even if you tire of the base game at some point (I haven't yet), there is much more you can add to TM. The Hellas & Elysium expansion is a double sided board with 2 new and different faces of Mars to terraform (ie different maps), so you have the option of 3 maps total. The Prelude expansion has additional cards and more importantly additional corporations, for even more variety. I have yet to get to either of these, but am looking forward to it when the time comes. There are also several others that I do not have yet.All this being said, the replayability is quite high on TM. And it's tons of fun if you like to think. There is a reason it's been in the top 20 on BGG the last 4 years since it's inception.EDIT: I forgot to mention that I highly suggest buying at least the 2 pack of wooden player boards from Smonex. They are great quality and completely take care of the problem of accidentally bumping/moving your production markers from the player boards that come with the game. Though not as vibrant or colorful, the wooden boards work so much better. Game on!EDIT 10/1/22: I have all the expansions except Turmoil, and I still love it. Favorite game of all time. Even better with the expansions; so much replayability.

If you're looking for a really deep board game - this should be your next purchase. I had heard good things about the game from a few people, and it had good reviews on board game geek, so I decided to give it a shot.BUILD QUALITYWhen it comes to the quality of the pieces and board, it's a bit of a mixed bag. The board itself is perfectly fine. Can't complain. For the player pieces and the currency pieces, these are actually quite nice! They're little colored cubes - some are translucent, others are a little shiny. I'm actually a fan of the pieces.My biggest complaint with the build quality, however, is the player sheet every player gets. This is where you track your "production" and your resources throughout the game. For starters, this sheet is a little confusing. My bigger complaint here, though, is that a portion of this sheet is dedicated to show how much of a given resource you earn every round. To indicate this, you put one of your colored player pieces on the designated number. The problem, though, is that the slightest of bumps on this sheet can slide the pieces around, meaning you can turn your production from a 3 to a 4, which can have a pretty big impact. I would have loved to have seen a physical slider piece, or little slots to hold the pieces.This complaint is not a HUGE deal, but probably my biggest concern with the build quality.INSTRUCTIONSI have to admit, when you first look at the instruction manual, it's pretty overwhelming. There are about 20 very dense pages of instructions to read through which walk through the mechanics of the game. It took myself and 4 other people about 2 hours to digest the instructions. We found ourselves referring to this manual often over the course of the game. The manual isn't the best organized, so answering a specific question about the game can often be trying to find a needle in a haystack. Further, the wording in the manual is often a little bit confusing and tricky to understand.One aspect of the instructions that I like is that they have a "beginner" version, which is recommended for the first time you play. Essentially, this gives every player the same "corporation", which removes some of the variability but makes it a bit easier to learn the mechanics of the game.MECHANICSThis is where the game really shines. While there is definitely a learning curve to this game, it offers so much variability in the way you play the game. There are numerous way to increase your "Terraform Rating" (aka, your score), and these actions you take ultimately progress the game in a super natural way.There is no designated number of turns that this game will last. There's no timer. There's no countdown. Instead, you are progressing towards making Mars into a "viable planet" to live on. You do this by increasing temperature of the planet, increasing the number of oceans, and increasing the percentage of Oxygen. The actions you take throughout the game may do any of these 3 things, either directly or indirectly. Sometimes, there are even moments where by increasing the temperature you increase the Oxygen level.Another really interesting aspect is the concept of a "generation". A generation is more or less a round of the game. Within each generation, every players takes turns. Each turn consists of up to 2 actions per player. Players continue going in a circle taking their actions until they have no further actions that they want to take, and they "pass". Once every player passes, the generation is complete.One dynamic I noticed is that the early generations of the game take quite awhile. People are figuring out their strategy, and are building the economy. However as the game progresses, the generations start to move very quickly and the game's resources start to increase at a must faster rate.Overall, the game probably took at least 2 hours to play.REPLAYABILITYWhat made this game so interesting, was the 2nd time I played. The first time was certainly fun, but was generally learning the mechanics and the basic strategies. For the 2nd time playing, though, we understood the main goals, but more importantly, we used the more advanced corporations. These corporations offer even more variation and customization about how you want to win the game.This type of strategizing is what really sold me on this game.CONCLUSIONUltimately, this game is quite complicated with a hefty instruction manual and a steep learning curve. But with the endless possibilities of how you want to play the game, the level of strategizing really outweighs the upfront cost, making this a really rewarding game to learn and to play.
