As you iOS folks probably already know, Ascension on the iPad is incredible. The ROTF expansion is great as well. Here's the BIG news. Today, Dominion was released on the iPad. It's not an "official" version, but all of the artwork and gameplay are there. And....
It's FREE.
You literally have no choice but to download this game.
Edit: Here is a short review.
