Video gamers! I need your help!!

[The D.O.Z.]

I haven’t played either of those so I couldn’t tell you which way to lean. But HL looks like a game you can always start up and have / find something to get into. EW looks like one of those “play it once, maybe twice for the trophies, and hardly play it again” types. I could be wrong though, as again I’ve not played either of these titles.
