On top of that, there's the fact that the system is so reliant on its unique GamePad controller – many games actively require you to use it rather than other controllers, and you can't even change your system settings without it.
This sucks. There is one game in particular I keep the Wii U around for. We call it Fronks but I think the real name is Islands or something on one of the Warioware games. It's a stupid game that easy to learn and always a hit at parties.
It's one of the few games that actually uses the tablet in a neat way. And because of that it probably will die with the Wii U.
