Which do you think to be a better game by the way?
I've only played a few games, so it's hard to say. They are very different.
Puzzle Strike fixes my biggest complaint about Dominion: the lack of direct player interaction. The components are great and so far I really like it. The asymmetric character powers also make the game a lot more interesting for me than Dominion.
Yomi is already getting a fair amount of play, and it really seems like a game that will only improve with time. The more I learn about the nuances of the game and the characters, the more I realize that it's quite deep and satisfying.
I'm happy I have both.
