or just talk about the games in general. Is Black Mesa better than the original Half-Life? What is the best Half-Life game? Why are the games still so good? How about the post-soviet setting? How about how cool it is that most of the main enemies are cops and troops?
I played HL2 for the first time when it was free recently. It was fun, definitely dated, but not in a bad way. Valve really cooked with the gravity gun.
