While I haven't played a lot of this year's games yet, I can't see any of them managing to unseat Shogun II. In terms of total hours played and surprise "It's not rubbish?! Oh my gosh - it's great!" factor nothing else comes close. It is my favourite strategy game and probably my favourite PC game of all time. Heh, and I only gave it a chance because TosaInu gently nagged me about it!

Worst game? Sword of the Stars II. Or do alpha quality games not count, since we're talking about full releases? :cough: Thank heavens I didn't have the money to preorder it.
