Pardon my ignorance of all things relating to Reiner Knizia, which it's now transpired that I should be ashamed to admit. Seems that there's quite alot of board games designed by him now ported to iOS, and they're all supposed to be excellent turn-based strategy games. But with so many to bite into, which one would you say should be the first one to get me hooked? I don't mind paying more money if one thoroughly deserves it, but would appreciate comparative feedback between these Knizia games from those who've experienced the games (either board game or iOS versions). I love playing TBS games, and can quite regularly win on Deity level in Civ Rev... but that's probably not saying much here! My only requirements are that the game runs stable, bug-free on iOS 4.1, and has offline single-player mode. Thanks!
