If I were you I'd look into the Wii library, as it has surprisingly many great games.
- Metroid Prime Trilogy - a must-have and a cheap purchase on the Wii U eshop
- Zelda Twilight Princess and Skyward Sword - Zeldas. Enough said. Just buy them. TP is more gritty and darker.
- Red Steel 2 - probably the best motion-shooting in a FPS
- Super Mario Galaxy 1 and 2 - two GOTYs. Some of the best games ever on any platform.
- No More Heroes 1 and 2 - OTT open world games with sword fights, very brutal. PAL version of NMH1 is censored though, so get the NA one.
- Resident Evil 4 - the best version of the awesome classic
- Xenoblade Chronicles - one of the best RPGs of the last decade
- The Last Story - another good jRPG
- Bully with motion cotrolls is said to be great
There are many more awesome games, but this should last you a long, long time and every single one of these games is still worth getting.
Wii U is a GCN 2 - I called it months before the release!
My Vita to-buy list: The Walking Dead, Persona 4 Golden, Need for Speed: Most Wanted, TearAway, Ys: Memories of Celceta, Muramasa: The Demon Blade, History: Legends of War, FIFA 13, Final Fantasy HD X, X-2, Worms Revolution Extreme, The Amazing Spiderman, Batman: Arkham Origins Blackgate - too many no-gaemz :/
My consoles: PS2 Slim, PS3 Slim 320 GB, PSV 32 GB, Wii, DSi.
