The best options are offered by EA Sports. Those are mediocre games, but if you want the full thing, they're the only options. Your other choice is to go with a lighter but funner football game, such as Flick Football or Backbreaker
Wow, it seems as if I've created a small following for Phoenix Wright... AWESOME! Let's band together and force Capcom to port the sequels as well!! WHO'S WITH ME!!!!!!?????????
Crap. Just wanted to keep the mometum going to help get us a sequel that we all want, but I guess not... Well, that didn't work. Well, there's one called "The Battle of (something I forgot)" that's a TBS-RPG hybrid, like Fire Emblem. It's an iPhone version of an iPad game, and it's going to be awesome. Other than that, can't think of any good RPG games besides the Zenonia games, Inotia 2, Chaos Rings, and the unfortunately pulled TNA.
Just wanted to add into the Phoenix Wright excitement, I will be getting it as soon as my exams end based on what I've been reading here and in the main thread. Consider this another victory .
4. ELISS! It's one of Toucharcade's best reviewed games and really original. It's kind of more action than puzzle, but I guess it fits in the catergory. One of my favorite games, and it's perfect for the iPhone.
