>>6413324>Custom Robo 3DSAs much as I would FUCKING LOVE THIS, Arena's sales didn't meet Nintendo's expectations, so a sequel is not too likely. The only new thing Arena brought to Custom Robo were wifi battles and the Diorama feature.
Perhaps if they DID make a Custom Robo 3DS game, it could have all the 4 player modes the GC game had, and include both the color customization AND the Diorama feature.
