Warcraft III?
would only cost you a couple of quid from a place like Gamestation....

The Elder Scrolls: Morrowind.. having just finished Oblivion
back to EVE Online again...
I put on my wizards robe, and cast N-N-N-NECRObUMP!

Oblivion again, but on PC this time (+Midas Magic, + Rebalance Mod)
Diablo II
ArmA
yeah, I like to take my time and appreciate the details of the levels and the game. you can pick up a lot of backstory that way

oh god yes. I'm still playing morrowind after oooh...two, three years?
do you have it on the PC?
if you, I recommend the Ultimate Galleon and Morrowind Comes Alive mods. Comes Alive puts in an additional 1000 or so NPC's: Trader caravans, bandits, just..extras.
oooh, thats an old one...
Ha, I'm now on my second replay of Fable: The Lost Chapters, the XBOX version. I love this game, as you have free roam of the world, for the most part, and can do as you will. Even cooler is seeing how your decisions affect your appearance, expressions, and even some of the spells you can use!
Oblivion and Morrowind; you'd love 'em.
plus, extra bonus points; moddable to an extreme degree; put in extra content, up to and including porting the entire Morrowind game and enviroment into the Oblivion engine, and being able to access both Cyrodil and Vvardenfell.
oh yes, and S.T.A.L.K.E.R, Prey and Gmod.
drat. I am playing S.T.A.L.K.E.R, Prey and Gmod.
...and Supreme Commander, Bioshock, Armed Assault, and CoD4.

tell me your specs, I'll tell you how it'll run

NB: both are also available for the Xbox (The Elder Scrolls III:Morrowind on the Xbox, The Elder Scrolls IV: Oblivion on the 360)
right now, computers are cheap; you can pick up an ATi 3870 for about £150, or an 8800 for about £120. if its got what you said above, and assuming its not onboard graphics, then it'll have...well...I mean, who are are ordering it from, and what is the budget?
So.. £500-£600...
'scuse me, just gotta do some research.
what will you be using it for, do you have network storage, and so on?
