I've seen reviews for a lot of deck building games (Thunderstone, Ascension, Arctic Foragers, Eminent Domain, Rune Age and more) and while I'll admit Dominion is the blandest theme-wise, none of the others seem to feel very thematic. Sure, the theme on some of them seem quite stronger than Dominion, but again, seeing gameplay of them doesn't make them feel thematic to me. Only exception is Mage Knight, but of course deck building is but a fraction of the game. I wonder why it's so difficult to make pure deck building games feel thematic? The first publisher to release such a game would surely have my money.
