Tactics. DO IT! No I'm serious get the PSP version, I believe it's called War of the Lions, best version out right now. Then do yourself another favour and pick up Tactics Ogre. I never really got the appeal of the CC series, but it seems too juvenile/ Japanese-cheesy to me. As for spin-off advice: In Compiliation of FFVII, stay away from Dirge of Cerberus. Crisis Core is an excellent game and Advent Children (movie) isn't that bad. The only other spin-off's I know of is Ivalice Alliance (tactics and XII are a part of) and Fabula Nova Crystallis (only XIII's been released so far). If your planning on getting the PSP FFIV collection, I'm right there with you! I plan to get it on release so I'll tell you how it goes.
