But there are TONS of great games on iOS!

Ticket to Ride, Carcassonne, NS Hex, Battle of the Bulge, Agricola, Does Not Commute, This War Of Mine, Spider 2, Tiny Wings, Prune, etc. etc. I've bought 100-200 games, many of them very good.

XCom and Pandemic are the ones that I've spent the most time on. The iPad is a fantastic form factor for board games, and XCom worked better IMHO on iPad than on console or PC.

There's http://www.metacritic.com/game/ios for recommendations. Works well. That said, discovery on the App Store is simply atrocious. Absolutely terrible and a complete embarrassment for Apple since the start. Even recommending games to me that I already own!
