Wind Waker HD and Mario Kart 8 recently. Though when I was younger it was definitely Crash Twinsanity. I must've beaten that game 10+ times, which is a rarity for me.
With friends, we always play Wii Party U and Nintendo Land. Even my sister who isn't into video games at all has fun with those. We used to play Call of Duty a lot but it was so repetitive that it wasn't really fun anymore, especially after Black Ops 2.
