Want to Expand my Games collection - help required.

Hey All. Just wondering what great games, new or old (not too old, not pre 2000) I should get to add to my collection. My current games are:

Supreme Commander
AOE 3
Company Of Heroes
Call Of Duty 2
Medieval 2
Battlefield 2142
Elder Scrolls: Oblivion

As you can see I mainly like RTS's, FPS's and RPG. I am already planning on buying Call Of Duty 4 and Crysis.

My rig is:
Intel Core 2 Duo E4400
2GB RAM (soon to be upgraded to 4GB)
Creative Soundblaster Xi - Fi Soundcard
ATI X1950 Pro (soon to be upgraded to a XFX 8800GT 512MB)

Thanks All. All replies and help fully appreciated.

The Witcher - Extremely solid, satisfying gritty rpg. Very worth it.

Call of Duty 4 - Short Campaign, but solid gameplay.

Neverwinter Nights 2 - It may be D&D, but great story and very fun. Lots of replayability.

Hellgate London - It may be a bit buggy right now, but it's addictive and full of good action.

Diablo II - It's a bit dated, but a classic that's worth playing through.

Crysis (if you can run it) - Speaks for itself.

FEAR - Absolutely amazing FPS.

Unrealy Tournament III - I haven't played it yet, but UT2004 was amazing and UT3 can only be better.

Thief, Deadly Shadows - Extremely fun stealth/action game.

Oblivion - Quintessential RPG.

Two Worlds - Another Oblivion style RPG, but with different gameplay.

Bioshock - Another great FPS with a good storyline.
