A whole lotta FFVII on my PSP, that's what!
I'm just 130,000 AP shy of mastering Knights of the Round and then I'll be making a trip to Cosmo Canyon to make myself some homemade Master Magic, Master Command, and Master Summon materia.
I've gotten all the final weapons (though I almost had a Magic Pot run away after stealing Vincent's from me earlier today) and all the characters using their lvl4 Limit Breaks. As I have KOTR, I bred a gold chocobo, which I named Jag [ :D ], and I also managed to nearly master all four Enemy Skill materia (I'm only missing Trine on one of them). Cloud's lvl99 and everyone else is really close.
All that's left before I jump into FFXII (something I've wanted to do for years) is defeating Emerald and Ruby Weapons (first time I'm seriously attempting it) and then pwning Sephiroth in his face. I've always loved how there's about a disc's worth of extra stuff you can do on FFVII's third disc. The story just "pauses" and you can run around doing lots of stuff for hours. I think I was at 55-60 hours when I swapped to disc 3 and now I'm currently at 81 hours or so. Anyway, I say about a week to a week and a half before I'm running around like this playing just about the most subtly naughty game I've ever played, hehe.
