Fantastic game! Just some thoughts:
Boss fights: Most were just OK, some were really good. I want more interactivity (like the final fight), how cool would it have been scaling/fighting on a dragon when you're fighting baldur for a second time.
More bosses would have been welcome. Fair enough not wanting to use more of the pantheon etc, but lol that hell's keeper was just a troll. Talking about trolls, there were a lot of them.
I have yet to dabble in the whole Valkyrie thing, but the one I did beat was a really cool fight. Are they all the same? Hope not...
Personally think the game ended decently, but there is so much more that I wanted to see or was hoping to see. But maybe that's just the game being so great: I can't get enough. I'm already craving some more GoW.
The whole Blades of Chaos reveal was amazing! The whole buildup got me so giddy and hyped, and it didn't disappoint. Saying that, I really really like the Axe, it's one cool ass weapon and may have dethroned the blades (soz)
