Valve should really consider removing the Halloween achievements, it's frickin' June
some bug where TF2 wouldn't show up in a mac library even if you owned it until it came for mac. I owned tf2 for pc, and when steam came out for mac it wouldn't show up. a quick look at the forums told me that it wouldn't show up until it came for mac, unlike other games where it just said "(not available)" on them.
