Maybe it's just me but I see an improvement in Crimson stage comparing it with the old stages... maybe I'm just seeing things lol
From a technical point of view it's indeed an improvement over the other stages. More details, better textures (though still nothing to write home about) and better lighting. But I also don't really like it's gritty, brown look. Danger Zone however looks a little underwhelming and I don't believe for a second, it wouldn't be possible on PS3 and Xbox360 too. :/
