It's pretty annoying really there are a few points that spring to mind from it:

1. if everyone would rather play single player...that's a problem isn't it? I personally find the multiplayer really bland, why arn't there more rpg elements to a multiplayer campaign? diplomacy? any depth at all? Risk with the option of zergy combat isn't much of a game it turns out.

2. They no doubt got there copys free, given that next to no ones actually making reviews/previews I'd say you wasted time that could have been spent by your fans advertising your game.

It's just all a bit disappointing really.
