I like keeping lists. They're very… organized. One list that I started last year, and that has only been growing since, is a list of games I have never played, but that I want to keep track of all the same, either because they are gaming landmarks I think I should try out or because they are wildly popular games and I suspect I must be missing out on something.

Here are some gaming landmarks I haven't played:

1. Beyond Good and Evil
2. Psychonauts
3. System Shock 1 and 2
4. Grim Fandango
5. Baldur's Gate 2
6. Planescape: Torment
7. Star Wars: KOTOR
8. Rez/Child of Eden
9. Everyday Shooter

Here are some popular games I haven't played:

1. Metal Gear Solid Series
2. Assassin's Creed Series
3. Grand Theft Auto III and IV
4. Halo Series
5. Call of Duty Series
6. Battlefield Series
7. Gears of War Series
8. Mass Effect Series
9. Demon's Souls/Dark Souls
10. Red Dead Redemption
11. Bioshock 2
12. Bayonetta

Thoughts? Which of these do you find to be my greatest oversights as a gamer? What other games could you not forgive someone for never having played?
