Coming from a Reddit AMA with 13AM Games and Dadako, the dev behing Pirare Pop Plus...
13AM: we think it's pretty cool. Dare we say "a switch in the right direction?" ( ͡° ͜ʖ ͡°) edit: realize I wanted to give a bit more detail I also think that it FEELS like my old SNES. Gathering around, playing games with a friend, that's something that makes tons of sense to me on, like, a base-level. If it's also powerful enough to run Skyrim? Super cool.
Dadako: I think it's a step in the right direction, I love local two player games - and have always wanted to develop more.
With both Guacamelee and Severed being fantastic games, I think Nintendo needs to hop on this request right away! I'd love to see what these guys could do with the new system.
