@Redeemer :
It's too much money for only paying one game !
I fisrt i found it great, but it became standard for me after some stages and boss defeat.
I dislike the very low resolution they used in PS3 , and the frame rate is not smooth you feel it really like some 30 FPS or under i think !
The animations are retro but they could have smoothed them, after some time with not so hight frame rate they look too much cutted or clunky robotic, too much for me personnaly. Well i didn't wanted to finish it at end and rebaught it,even if i was very happy at beginning !
Just to avoid you some disappointment perhaps

Yes, Halo could be remake that way, with blocky retroo characters why not !
