iPad game recommendations

Hey guys, I had an ipad 1 for about a year and then last month got an ipad 3. I'm on the quest to find *lengthy* iPad games. I don't really care about the genre, simply that they're not simple games like temple run or jetpack joyride, or turn based games like hero academy. I'm looking for games like sword and sorcery ep that have a campaign and require a lengthy sit down to play.
