The lights are on
Yeah, I don't know. This'll sound weird but to me, the Wii looked sleek and very well designed. I think I read a few editorials from other game sites and magazines that made mention of how the Wii almost looked like an Apple product. It had clean, simple, and attractive design. I personally loved the Gamecube and it remains my favorite Nintendo console to date.
The Wii U doesn't look bad, but it's just not very distinctive. But then again, what looks more plain than the PS3?
