I thought IU was a decent game. Severely rushed and unfinished yes, but I enjoyed it. It could have worked a bit more on fleshing out the world(as in secrets, field hazards, ect), Connect skills, Enemy AI, and the secondary characters that join in the end. Overall though, the game bought back old school elements and envronments that actually felt dangerous. Shame MS rushed the game… Same thing for Radiata Stories.
Star Ocean 4 however had absolutely no soul in it. It's probably one the the worst tri-Ace games I ever played and this isn't on a list from favorite to least favorite. Too much rehash of cheap spamming battle elements, very limited Item Creation,worst bonus dungeons ever , worst main character ever, and a "power of friendship" mood in a place where it does not belong. I suppose an otaku can get a charm out of it, though Bacchus and Welch were not bad.
