So I have now finished God of War: Ascension and gotten the platinum trophy. Given the fact that some people had told me this wasn't going to be possible to do in a day I feel pretty good and accomplished.
100% the game, all trophies in a single play through. Only missed 1 collectible on the second chapter which I went back to after and in less than 5 minutes I got it.
Contrary to what I said on my last comment, the second half of the game wasn't as difficult for me as the first half. Maybe its because I had gotten better at the mechanics and started actually using block and dodge...
Overall, pretty good game. There is almost no dialog/story so it is just a game about how awesome it looks but the little story that was there I believe was worth the game.
Only thing I didn't like about the game... too many sliding mini game things. That got boring quick for me
