No, seriously... I think its a pretty standard thing. Even Halo 3 had this down 15 years ago.
Why isnt there a boxing ring mode where everyone has power gloves on? Why isnt there a Shovel/Lollipop mode where everyone has shovels/lollipops and you cant throw normal attacks, so you have to KO each other? Why isnt there a Ninja mode where everyone has Nunchucks? Why isnt there a mode where there is only Ice/Stun guns?
This is basic stuff... I think the game modes right now are way too basic. The game has so much potential but lacks basic creativity...
