The Conduit got a lot of post release flak, and I'll be the first to admit that the single player sucked loads of donkey butter by the halfway mark, but what made the game for me was the multiplayer. I really can not explain why, but online multiplayer Conduit was some of the best fun I ever had with an FPS.
I know how Yahtzee feels about judging a game on its multiplayer, and I really agree with him that unless the game is something like Mario Party, the single player should be the yardstick by which the game is measured, but if Conduit 2 has multiplayer, you can bet your ass I will buy it just on those grounds alone.
