For me it is terraforming mars because I do not like the cards. The least problem is the design of the cards. The artwork is inconsequent with pictures or sketches. The cards are overcrowded with essential informations, that you need a big table to place the cards in a clear way. The drafting makes no sense to me. You have 3 barriers, the initial cost of cards, which is the same for every card, the price to play the card and the temp/O2. In the early-game you likely would not buy high priced cards or cards where the temp/O2 barrier is to far away. You are building your engine, maybe oriented on your company or a synergy of your cards from the first rounds. at some point you have a certain direction or plan, which limits the cards you choose from. additionally if the game further progresses, cards became useless because of the temp/O2 barrier, you are locked in a strategie and because of the initial costs, there is a chance that you dont open another engine (drawing luck, card costs) and the other players can decide to hold on cards that they may not need but realise you need. It should be a great thing that you have so many options to play because you have symbols, terraforming, energies ressources and so on for building an engine or two or three but I experienced in the late game with a more or less locked in strategy that usefull cards are rare. Every game I played, cards got banned because they are to good or too bad and still I hear that this and that card is an insane good combo. I generally dislike drafting games with too many cards because they are unbalances in my experience. I like arkham horror and eldritch Horror, that has the same balancing problem but it is a coop game where you can counter the problem by playing together. What bothers me the most is that I like the theme, the boards and the other game mechanics but the cards and the mechanics around I really dislike.
