Wii U: Nintendo kept own devs in the dark

[Zlejedi]

What do you guys mean by a lot of time needed to use that second screen well ?

It's trivial actually.

You can't use it for anything significant for any multiplayer game since there's a chance someone will be using this screen to play game.

If you are making single player only game then you put inventory, mini-map etc on it or use it as tablet for Okami clones ;)

Also is that Nintendo dev a total moron who lives in a cave and never heard of pc gaming ? Pc games have been designed for last 15 or 20 years with multiplayer where people don't see each other screen.
