Open your Steam games library right now. Go on. Just do it!
Right, now look through your titles, like, some of the ones you feel you play the most. Then look at a few others. You might be surprised, I know I was.
Then post up here where you thought most of your time would lie, and what surprised you.
I was thinking Half-Life would be well up there, what with me working on The Core and being a ProGoldsource guy in general. However, it's sitting at a fairly meager 55 hours.
I figured it would be higher than the counter-strike series anyway, seeing as I'm not a big cs player. CS1.6 and CS:GO beta are fairly close to one another at 12 and 11 hours respectively and CS:S is just... 179 HOURS!? I have considered however, that a lot of this could be testing Archie's maps, dicking around with bots and whatever else. Still, 179 hours accounts for a whole fuckton of dicking.
Then there are the obvious time black holes, the free-roaming RPGs. Fallout 3 was not on purchased on Steam but I know that's way up there. New Vegas is at 189 Hours, Skyrim at 170... Fuck. Not counting Fallout 3 that's already over 2 weeks of my life sunk into Bethesda titles. Sad thing is, I'm yet to finish either of those games, and I need to start the Mass Effect series after that...
Anyway, that pretty much covers the major ones. A lot of my other games are sitting around the 30 hour mark and then there are the bottom feeders, some because I just don't feel like playing them and others because I haven't got round to it yet.
Worms reloaded - 8 hours
Duke Nukem Forever - 11 Hours (and never likely to move from that spot ever)
TF2 - 13 Hours
Operation Flashpoint RR: 4 Hours
Just Cause 2: 2 Hours
Metro 2033 - 59 minutes
Seems I need to finish the games I've got rather than complain about the new ones I can't afford... What's that? E3 starts on the 5th? Fuck.
tl;dr - I play a lot of games, now get out of this thread.
