N64 "Beetle Adventure Racing" is crazy fun! Race against the clock to improve your time, race the computer, race another player, and best of all are the wild Arena battles - up to 4 players. This was always big fun at family gatherings.
Wii "Godzilla Unleashed" is my favorite solo game. I'd run the sound through my home theater and crank up all the lovely authentic Toho kaiju roars, screeches, howls, and destruction. Controls varied slightly by monster but always felt intuitive. Battling other beasts could get a little glitchy in tight quarters but knock a few buildings out of the way and all's well. Greatest cathartic stress reliever, ever!
