I have been playing Half-Life once again. I think it's pretty damn addictive and aweosmely fun, although there seems little storyline to the whole thing and it's more blast your way through everywhere than HL2. Stuck at a stupidly hard part though, a huge alien that hears where you are and pecks away at you with a razor-sharp beak or something and totally owns you with it. Slightly annoying, but fun all the same.
