Well I can't say I can comment on how it compares to Amalur since I haven't played it yet. It looks fun but the story seems too shallow from what I have seen for me to spend the full $60. Plus I am a little preoccupied with FFXIII-2. I can forgive quite a bit when it comes to action if a game has an engrossing storyline which is why I liked Nier so much.
Amalur has a lot of its own problems, i was just focusing on the action combat specifically. It has a lot of strategic depth that isn't present in a game like Nier, which is very brutish and unelegant altogether.
I guess sort of related, but how close to the PS3 version did the development team manage to get the 360 version of this game this time? Thankfully my fiancee got me the PS3 version, 'cause I am assuming it was the best again, but are there any real differences? Framerate the same?
