Below are a few Nintendo Wii and Nintendo 3DS video games currently on sale, or for pre-order, on Amazon.com.
Mrs. Coffee purchased me Donkey Kong Country Returns as a Christmas gift, and we thoroughly enjoyed the game's cooperative experience. If you are looking for a challenging and fun platforming game, I definitely recommend Donkey Kong Country Returns.
Other than DKCR, I have also played and beaten Resident Evil 4 on the Wii, though it's no longer in my Wii collection. I enjoyed Resident Evil 4, though I didn't feel it was very "Resident Evil" compared to the older games in the series, but I would recommend it to Wii owners looking for a lower priced game from the Resident Evil series.
Are there any games listed below you would, or wouldn't, recommend to other Wii and 3DS owners?
