The game was filled with win: the beginning sequence, the bosses, the artistic design, the controls, the rock-solid 60 FPS, the lore entries, the enemies, the characters, the title screen, etc. You know they did something right when one of the biggest complaints was that the doors were sticky.
The levels were great. Even the relatively vanilla Norion looked great and felt right. Phaaze was nice, too (at least what I saw of it, with one eye constantly watching that stupid Phazon gauge).
I think one of the things that makes the relative difficulty of the bosses go down as the game progresses is the fact that you can go and find so many more optional energy tanks.
One more question...does anyone know if you have red and blue credits left over after buying everything? Or do you need to get every single red and blue bonus to get all the stuff?
