Tactical RPGs can be like that too. And some have overpowered characters, like FFTs' Cid. He can practically win any battle by himself. If you don't mind playing in Japanese or playing translated roms, the Super Robot Wars games are pretty good. Most of the games NIS puts out are tactical rpgs but of course the main one is Disgaea. The game requires a lot of level grinding and weapon upgrading though. Recently got Makai Kingdom & that one is pretty fun. The Romancing SaGa & SaGa Frontier games aren't action rpgs or tactical rpgs but they do require some strategy. You don't have levels, you get stats randomly from battle, you learn skills by using your weapons in battle, & the random battles are based on your characters strength, the stronger you are the stronger they are. Also they have multiple main characters, storylines, recruitable characters, & side quests. Legend of Mana, Sword of Mana, & Seiken Densetsu 3 are some good action rpgs. Secret of Evermore is really good too. Grandia, Alundra, & Parasite Eve are pretty good, but I've only played the 1st games. Threads of Fate. Saiyuki Journey West. You said you played Star Ocean 4, the 1st 2 are my favorites of the series. Also the Tales series is sister series to Star Ocean.
