The PC list isn't 100% complete. These are just the games I have installed. I still have all my retro PC games like Doom and Duke3D that I'd need to find the disks and keys for so I left them out for now.

It's amazing as I'm sure alot of you know, that the more games you have in your collection, the less gaming you do in general. Alot of these games I have installed or purchased and never got around to playing them at all. Would love everyone to share their collections though so I can get a good idea of what I'm missing.

I'm pleading the fifth on this one.

PC (Just listing what I have on Steam):
Torchlight
Civilization 5
Mass Effect
Mass Effect 2

PS3:
Uncharted
Batman: Arkham Asylum
Infamous
Prince of Persia
Final Fantasy XIII
Little Big Planet
Mod Nation Racers
Grand Theft Auto IV

It feels like I have another PS3 game I'm forgetting about... anyways, I don't buy games unless I plan on playing them in the very near future. Mass Effect 1 & 2 I got during the holiday Steam sales but I've wanted to play them for a while. I was playing Grand Theft Auto at the time (beat it yesterday though) and then I'm borrowing Uncharted 2 from a coworker today but after that I'll start them.

I have a few friends that are like you Phonix, where they have tons and tons of games but then don't get around to playing all of them. Other games they buy when they come out and by the time they get around to playing them they could have bought them for half the price. I don't get that personally and most of the time I buy games they are already a greatest hit or whatever on sale. :-\

Steve-O you can only plead the 5th ammendment in the US!

you're collection to large to list? I only have a handful. Only ever had a handful, Gave some away to a friend of mine cause I dont play em anymore( BF1942, BF2, BF2 expansion etc)

The only games you would find on my desk now are unreal tournament III, Call of cuty Modern warefare, MW2, black ops and battlefield bad company 2.

We do have section 13 http://en.wikipedia.org/wiki/Section_Thirteen_of_the_Canadian_Charter_of_Rights_and_Freedoms

13. A witness who testifies in any proceedings has the right not to have any incriminating evidence so given used to incriminate that witness in any other proceedings, except in a prosecution for perjury or for the giving of contradictory evidence.

Yes -- it's not a trial, but I'm not listing ISO's heh.

lmao Steve-o ! good one lol

AH I also have section 8 tho I didnt play it much.

Wow! I was thinking everyone was going to chime in with lists 10x bigger than mine. Now I feel a little silly lol.

In the same breath, it's a COLLECTION. I can get away with having this many if I just call it a collection lol. Most collectors collect things and they never leave their packaging so yeah I guess I fall into the same boat as them.

My collection is tiny.

Nintendo Wii:

A few hundred handfuls of games...

LOL I guess I should have listed my Wii games too. Good thread though, maybe now that we know what everyone else has we might be able to put those older/deader games to use some night.

We really should all get together with a common game some night and duke it out. I'm sure it wouldn't be too hard to organize.

Updated with about 40 new games.
