Nintendo has owned couch coop in comparison to the competition. Luigi's Mansion, Pikmin 3 and Mario 3D World are all excellent coop games.
In terms of favorite all time couch coop, Mario 3D World by a very long shot.
Hi @Chrkeller Would you believe if I told you I had no idea Mario 3D World was Coop? I have it on the WiiU but honestly I didn't like it much for whatever reason. I think I might just have to revisit it if you say it is your all time favorite coop.
Thanks for the insight.
