Obviously I had a Wii, was here during the NintenDomination. Still the reason why I bought a WiiU at launch was the Wii backwards compatibility. I was moving away to the Netherlands and I could not really take the Wii with me, instead of getting a cheap Wii decided to invest on the new console.
The first six months I was mainly playing with Wii games and NintendoLand. It was during this time that I saw how badly Nintendo implemented the backwards compatibility... even though they did do some of it years later.
My Wii collection is around 60+ games (here's an incomplete list due to VGC database destruction), and my current WiiU collection stands only at 25. I'm guessing my final WiiU collection will be half of that of the Wii, and that drop will be mainly due to the third party exodus (half of my Wii titles are third party).
BTW, nice topic
