Ok, I've never played it. Never really had a computer of my own that could handle it. Well, I got a hand me down that I can finally play it on. I searched on E-bay and my god man, what the hell am I supposed to buy? There's red, blue, Counter-Strike, mods, gold versions, multi-packs, GOY stuff, etc. All I want it Half-Life....exactly what I would've bought in the store when I first came out. That's it. No expansions, no mods, zip. Just....Half life. Can anyone steer me correctly. God I hate PC games....
