I don't a fondness to Borat. I don't how it did outrageous; haven't they ever interneted? We have Goat's Sea and Celebrating Lemons. - Gandob

The Sims 3
Hounestly, I hate this game, because EA never gets it to work right on macs. Do they do any quality assurance? At any rate though I remembered when I played the sims and it worked and it was very addicting. Endless things to do. Give me the sims with expansion packs and I could definitely put this on the list.

Team Fortress 2
Another game that doesn't have an end to it, I feel like only games such as these can be long-lasting and be a good choice for a list like this.

Dragon Age Origins or Dragon Age 2
These games have huge replay value. I could spend a very long time going through every possible outcome and trying out the romances with everybody. It goes on the list.

Playing only 3 games for the rest of my life would drive me to madness, regardless of how good or addictive they were, so I'll go with the games I've played through the most and will play again

Castlevania: Symphony of the Night
Super Metroid
Final Fantasy Tactics

if only there is a COD collection

Skyrim
Final Fantasy IX
Borderlands GOTY Edition
