If I'm stuck with 3 people, and we don't have internet, then it's all about 4 player local multiplayer games. Easy.
Wii:
Mario Kart Wii - for the 4 player local racing.
GoldenEye 007 - for the 4 player local shooting.
New Super Mario Bros. Wii - for the 4 player local platforming.
Rock Band 3 - for the 4 player local music, with piano, drum, and guitar lessons.
Wii Sports Resort - for the 4 player tennis, golf, bowling, frisbee dog, and staying in shape.
It's just too bad I don't have room for Smash Bros. Brawl or BIT.TRIP BEAT. Those games are great for 4 players.
If I were alone, it would be all about a PC with some games that last forever, like Minecraft, Civ 5, The Orange Box (if that's cheating I'd just take Portal), StarCraft 2, and hm.... not sure... maybe Ancient Domains of Mystery. I played it on and off for a decade and never beat it. If I was alone on the moon... I'd destroy that game.
