I buy Terraforming Mars (never tried yet) and CloudAge on sale to give it a luck (the universe look cool).

I tested CloudAge in solo, just to get the flow. Took me 1h to finish the first scenario. Not all mechanisms are given on first scenario which (of course) feels kinda flat, but it's perfect to learn rules slowly. The game is cool, but what seems even better is the tiny campaign that slowly adds mechanisms and card in a story driven way. The campaign is supposed to take 7 plays and I will definitely do it.
