Over $20? I thought $9.99 was the max? Well, anyway, I guess Doom Resurrection should be mentioned, along with Rolando 2 and Real Racing.
+1, get spore. Probably the best game on the app store. I still find myself coming back to it. It's just so fun.
Real racing, although most of my favorite games are cheap: flight control, drop 7 lite, big top 10, lock n roll, deer hunter
Your question is off-topic. Maybe you should try searching the forum or post the question as a different thread for more visibility.
Zenonia, Peggle, Real Racing, Doom Resurrection, Fantastic Contraption, Sway, Puzzle Quest. Most of those are in the 5-10$ range.
Real Racing is the best $10 app on the store, with Rolando 2 being a close second. Otherwise... I think most really expensive games on the app store are just overhyped crap made by big name developers. I was so unimpressed with NFSU, and I don't own another EA game. I got it because everyone recommended it, but I spent a max of an hour on that, and then went back to my favorite, small, inexpensive indie games like Saucelifter, I Dig It, and Westbang.
As you don't play nfsu anymore... Could I borrow it from you ? I am a BIG fan of these Arcade style racing games
