Running Garry's Mod 9 with TF2?
I just got TF2, and I wanted a copy of Garry's Mod to go with it. However, I was too lazy to pay for it, so I got the free version of it. However, it said that I SPECIFICALLY needed HL2, HL2 Deathmatch, And CS:S. I've restarted Steam, but it doesn't appear on my Games list. Do I really need those games mentioned before, or will any Source game do?
