I have no doubt the game is great, like I said I've bought every other H&D game made, and loved them. I know I'm missing out on a great single player game, it's just that I feel a statement should be made. That's our right, and our duty really...if you don't approve of a game then the only way you can make a statement that will garner attention to the manufacturers is not to buy it.
If they would go ahead and say that a future add-on will include co-op, I'd go ahead and buy it on their word (even though they've lied in the past on such issues). As long as they are vague about co-op (as they were leading up to the game's release), I'll just hold off with my money or find other ways to play the SP.
btw it's "you're alone" :p
