Same here, I was just finishing university at that time, and it seemed like every student house had a Wii for party games, and for casual gaming while drinking and getting ready for a night out. Aside from that, I remember guitar hero being popular.

As for the Wii U, I think most people my age just moved on to a different step in our lives, we get together less often, and there just isn't the same interest or opportunities available for casual gaming with friends. I don't know what's happening with the younger generations, and what they're doing in university now.
