I don't know if it's just the fact that FFXIII is almost here, but I have a strong urge to get into an RPG.  I've played through Dragon Age and Oblivion, but I really want some old school 2D stuff. It just seems so much more appealing to me right now.  So what i have to choose from is Chrono Trigger, FF6, or FF2.  I'm looking for some suggestions on where to start first, (I've never played a significant amount of any of these) from those who have played them before.  Chrono Trigger seems like the easiest to get into for some reason, but I'm really curious about the earlier Final Fantasy games. 
 
Also, any other RPG suggestions? Especially any with a Star Ocean 2-like battle system?
