Yeah, I got CS:S HL:S, HL2, HL2 Deathmatch, HL2 Lost Coast, and HL1 Deathmatch for $40 at Wal-Mart I think. I'm like 1/4 through with HL2 and I'm amazed at how excellent the graphics are for such an old game. It can even bog down my computer if it's not overclocked very high.
And I just got my dedicated server to work, so if anyone plays CS:S you can add me as a friend, me and THEpiGUY are trying to get some online games set up and we're looking for more players. PM me for my account. We need to do a CF CS:S game night this coming weekend or something.
