Well, I just finished the PS3 demo, and the game seems all kinds of solid.
I was very late into God of War because I got hung up on the bastardization of beloved (to me) Greek mythology. I'm not going to let my similar outrage here turn me off to what's shaping up to be a decent enough game. If nothing else, I like the duality of the finishers and skill tree systems. Seems to lend itself to a better than decent amount of customization.
Sure, it's rote and by the numbers in some respects, totally disrespectful in others. But I figure if I could get around my misgivings re: the God of War series, then this game should pose no additional barriers.
Also, on a semi-related note, this is how you do a demo Sony. There was a decent 20-30 minutes of content here. I figured it'd end with the Death fight, not continue for what felt like most of another stage after that. By comparison, I think I cleared the God of War 3 demo in like five minutes.
Preordered the PS3 Divine Edition, and I'm taking a risk on preordering the PSP version as well. Oh, I should probably order the anime, and complete the sodomy being inflicted upon the literature.
