Since someone mentioned originality before, I will say this:
I was playing it earlier tonight, and my wife (who plays enough games with me to know what she's doing) walked past the TV, and after glancing at it, asked me what part of Oblivion this was.
I called her a dumb broad and sent her back to the kitchen (not true), but afterward it sort of struck me how it could totally appear that way. First person, melee weapon in right hand, magic in the left. Look fast enough and you really can't tell the difference between a splicer and an imp. Here you hack, there you lockpick. Even the HUD. They call it Eva, but it's really just a art-deco mana bar.
I do think the game is very original, but its funny that there will always be some sort of gaming conventions that will never change.
