Well, I've never beaten either of them, or any Star Ocean game, for that matter.

In 3 (Till the End of Time) I stopped after I had gotten to disk 2, should I start playing it again (I don't have a PS2 so I'd have to emulate it)?

In 4 (The Last Hope) I only beat the first boss on the beach. The game looked beautiful, but I just didn't really want to play it, as I had been mega-obsessed with WoW at the time (More casual now ). I do have a PS3 so I can easily pick up a copy.

Which should I start playing again?
Also, would you recommend 1 and 2? (Psp version )
