Terraforming Mars: Ares Expansion!
I rarely back Kickstarters for my personal use, but I love the base game so much I had to back the expansions. And buy the sleeve packs. And the board upgrades. And the promo cards. And suddenly I was at $119 for a $30 game. WORTH IT!!! This is two really good expansions to the base game, as well as a third that turns it into a co-op game. The main upgrade to the game is new Phase cards - some project cards will update the phase cards and give you better bonuses. There are now also end game victory points and milestones you can earn along the way. The reason these expansions are so great is that they don't CHANGE the game - they just add a little more to it. Just some smaller tweaks to keep the base game interesting. But the Crisis (co-op) mode... Oooh boy. I played this solo on repeat for a full day and night, then started again in the morning. You start with Mars completely terraformed, and every turn a new crisis card tells you what decreases and what new cards you need to play in order to stop the crisis from happening again. Like any good co-op game, you've got to split your actions between fixing the problems and improving yourself so you don't get buried. In all the games I've played, I won twicce (easy mode), lost a countless number of games, and put a big asterisk on one game when I completely misunderstood one vital rule. I rarely like solo games, but this one has just grabbed me and isn't letting go.
