Seriously though, all out war isn't this 'no interaction' shit, just imagine the REAL all out war
>Niji vs Holo baseball
>Niji vs Holo war in Minecraft
>Niji vs Holo mahjong team match
>Niji vs Holo Mario kart tournament
And many more, hell, just have them play sport against eachother in 3D, several Niji already did that.
