Which should I get?

The games I have bought so far are portal 2 and kotor. Wanted NV but missed the sale. Games I'm considering today: Limbo, Civ 5, overlord complete or a tom clancy game (have none of them). I should only get 2 games as the winter sale is coming,also I might get something tommorow, so what do you suggest?

Edit: Do the older ubisoft games have the DRM?

In the sale should I get Fallout New Vegas or wait and see if Fallout 3 goes on sale.

Should I get the unreal deal pack or just one unreal game?

I have a friend who is a bit of a pc noob. He just got into gaming with it and is looking for a few games. So far he's enjoying minecraft. On console he likes halo and assassin's creed. His specs are something like a dual core 2.1 ghz processor (might be dual core)and 2gb ram. To give you an idea of what his pc is like he can run portal 2 at max settings according to system requirements lab but cannot run Batman:AA or Mass effect at all. Can you recommend any games for him (his birthday is coming up).

To give you an example for me Borderlands is £5. BTW, thnx for all the suggestions so far.

What is the best pc game on steam right now for £5 or less?

The originals, heroes or Dark Messiah? Which is your favourite. You can just pick out a specific game and say that was your favourite all in all if you want.

What about the platinum pack? It comes with DoW gold and Dark Crusade for the same price as the gold pack.

Should I get DoW platinum or should I save my money?
