Hello, I've been pondering about acquiring a Wii U.

If I do come to a conclusion to get one, should I consider getting popular online multiplayer titles, such as Mario Kart 8 and Super Smash Bros, too?

Since Wii U hasn't been officially releases in the apac region, I'm worried about logging into barren lobbies most of the time or playing against high latency players from other regions.

By the way, is the Wii U's online multiplayer region restricted or is is game specific?
