Finally beat God of War. Tonight I learned that my wireless PS2 controller wasn't really up to the challenge of defeating Ares. (The final battle required thrashing on one button pretty quickly and I guess the wireless controller couldn't send a signal fast enough to handle it. I switched over to a wired controller and beat it shortly thereafter.)
There were some frustrating not-so-fun bits towards the end but overall it was a very good game. It'd be tough to make a direct sequel, although it appears they've got plans in the works already.
