Pretty much.
Heck, Some people are like me and don't like being tied to a TV while still wanting to play at home.
Well, personally, odds are I'm spending most of my time (by my own will) in three places in my house:
- My room
- My living room
- The room where the computer is at.
If I'm at 1 or 2, there's an Xbox and a TV there (my Xbox is in my room, my brother's is in the living room). Generally if I'm at 3 I'm on the computer.
The other places in my house (bathroom, dining room, kitchen, and other rooms) I generally don't go to often or don't stay there often. Or I'm usually preoccupied with other things like taking a shit or fixing a sandwich. If I'm going to be playing a video game in my house it'll be in a room that has access to video games. No, I don't enjoy shitting while playing Mario if you're wondering.
If I'm somewhere that's not those rooms and I'm playing video games it's either out of the house (which nullifies the Wii U controller) or at a friend's house. And my friend's are smart enough to both not buy a Wii U and fun enough that I don't need to play a video game on my own there.
So outside of the occasional poop-and-play that some people do, I don't see the use unless you're like ten and your house is so busy with other people using the electronics that you can't access your own crap.
