co-op would be a hard one to work around... fun idea though.
and no apology needed. i just felt like you were being a little unfair by judging based on how the game looks, not by how it plays (glad you specified... even though it could entirely be a skill issue. ^^) the base game is hard, kind of. i play with mods so it's harder and i don't really have any trouble, but everyone has a different play style i guess.
