Dominion is the the most popular deck-building game. As much as Magic introduced the collectible aspect, Dominion popularized the concept of deck-building as core gameplay as well as selling complete boxed sets of 500 cards, rather than small booster sets. Dominion is wildly popular and multiple fanwares have been created for Android by Ankur Mehta, iOS by Hammer Technology, and for Windows by Jeff Till. There is an official version in the works for the iOS.
Dominion is more streamed-lined and smoother than Thunderstone at the cost of less color and narrative. Which is better...is a matter of taste.
