Just beat it after a marathon session. I was a little worried that I'd fucked myself by saving on the moon because you come back from the moon and go straight into the robot that comes out of the tower of babel and a few of the enemies in there are motherfuckers (the little lasers) and I didn't know if I could even make it to the save point. Also, the attack node of the CPU fight killed me before I could get a spell off probably 3 times by chain attacking. The 4th time I got slow off and after that the fight was easy. I had to grind some on the moon to be able to explore in the final dungeon. Once I started getting a few levels and upgrades things fell into place, though. It was just hours of shell/protect and slow/stop. I only picked up a couple augments because I didn't understand how they worked and skipped some things (the summoner place, for one, so I didn't pick up any summons, Excalibur, didn't get Yang's augments from the Faerie place, etc, so the game could have been a lot easier. It probably would have taken a bit longer, though, and I wanted to beat the game today.
