Buying stuff of steam. Could use an opinion.

So I want to play something off steam on this fantastic christmas. I want to get one of the older fallout games but I am not too sure if they are still accessible. I have some stuff but I was wondering if I should get some fallout or something else?

L4D1 ? or Orange box : D

Already got both :P Thanks though.

Torchlight 
Braid 
Monkey Island SE 
 
Some of the best Indie/Casual games are literally a couple of $ and £'s good time to pick up on games you may have miss. I've already spent like $20 and got like 6 games

I know I have spent like 30 bucks so far. Steam is kind of crazy. I got Torchlight and am really enjoying it.

The battlefield 2 package is only 8 bucks.

if you like Rpgs there is The witcher  :O 

I can also really recommend Aquaria and the Shadowgrounds pack for the lesser known games. 
 
Aquaria's really really up there though.

Cool! But I kind of really want Fallout or Fallout 2 and I am just not sure if I will enjoy it.
Also is Trine any good. Brad use to talk about it all the time.

Steam has the Fallout Collection, which includes Fallout 1, Fallout 2, and Fallout Tactics for $20.   Sadly, none of the Fallout games are on sale right now.
 
As for Trine, there's a demo up on Steam.

I second that, Slip.
