@ShadowLegend300: I'm really not sure if it does amount to that many games. There seem to be many users around who's list collection numbers into the hundreds, sometimes for just one platform. Not that I'm saying that's a bad thing for me, but given the amount of time I've spent reading about and thinking about games it's maybe surprising.
No, I did buy them in the Orange Box pretty much on the day of release but I think it's more important to list the actual individual games I've played rather than deferring to the form I bought them in. Also, there's so much to write about those 5 particular games that it would be silly to bunch them up - they deserve their own paragraph.
