I've found Wii U games to be pretty good in small chunks and playing on the screen certainly helps me fit in more game time than I usually would.
I haven't switched my 360 on in over a year, just couldn't fit it in around being a dad for the first time, working and sleeping. I'm making an effort to play through the last of the 360 games I now have left (after a clear out) now that I get a bit more time in the evenings.
But gone are the days when I could just play a game most of a Sunday.
