Just wanted to tell you that Rocket League is more uniquer and funner and and adictiver and even more differenter from other experiences than Splatoon.
So Splatoon isn't even close to a contender for GOTG. Unless the contender list is 200 games long.

So why is Splatoon best multiplayer game 2015 but rocket league not? Please explain....
