This Securom stuff is ridiculous. So often you see developers remove it in patches soon after release, so what is the point of having it there in the first place? The only people you'll inconvenience are the very casual gamers who don't even bother looking for patches. And especially for a game like HL2 with all the extra piracy measures, using Securom as well is pointless. I guess I should be happy they've removed it now, though. Decent of them.
