- Hyrule Warriors ----> It was actually quite fun playing it with my 5 year old brother. We just keep telling each other where to go and stuff.
Knew I was forgetting one, exclusively played co-op with this game's story mode.
Also beginning of this gen the only thing I played for months was NintendoLand and co-oped the hell out of TLoZ Battle Quest during that time.
@Rine: Arigato :)
