well.. if you have never played Dane's inferno then you really couldnt know how good it is
I have no doubt that GOW3 is going to be a great game ,but that's not enough reason for another game to be lame.
The reason i say DI is lame, is because (judging by the demo) it is a stripped-down, lazy, less action-packed version of the GoW games. Theres not enough distinction imo. Even the bloody environments looked the same as GoW in the game.. lame. I don't mind when games borrow from each other, but a almost direct copy is pretty lame imo. Shows little innovation.
