Well of course C2. Goldeneye is just another CoD if you ask me, it has a pretty good selection of modes, but Conduit is going to be way more polished.
Conduit 2 without a doubt when you compare it to GoldenEye. It would be a tough call to decide between this and Black Ops though. I would have to play Conduit 2 first.
GoldenEye - 0
Conduit 2 -7
Don't Know - 1
