I'm late but I gotta say I read some great recommendations. If I had to name my favourite Wii games I would name:
- Donkey Kong Country Returns
- New Super Mario Bros Wii
- Punch Out!!
- Fire Emblem: Radiant Dawn
- Super Mario Galaxy 2
- Resident Evil Remake (that if you ever played the original and never the remake)
Those games are so good that there is no I'm a HD whore excuse to them.
