I'm serious though. I have played online in the past. And I just simply get nothing out of it.
Nothing beats an enemy that can "think" - and better yet, if the other team actually works as a team.
With single player games, most of the time the computer artificial intelligence (AI) is just plain terrible. The scripts are just that, "scripts" - once you see how the enemy is going to react, difficulty drops.
With multiplayer games, there is no AI, there is no script, every game is different.
