Just a rough guess though

Honestly I have a lot of games, but among my favourite are: Skyrim, The Witcher 2, WOW, Risen, Assassin's Creed 3, Far Cry 3 ;)

I don't sell games so i have every game game I have owned for last 25 years so tones

I don't consider myself a collector. I must have add when it comes to games,because I could never own as many games as some of you have. Once I beat a game,are get tired of it,then I see no reason to ever go back to it. I don't think I've ever owned more then 10 games at one time. ever. I used to rent from blockbuster,when they were still legit,but all the ones bye me,have closed. I guess I could do the gamefly option,but I don't do are pay for anything online,because it of my fear of getting hacked.

36 PC
20 DS
17 Wii
12 GC
10 Sega Genesis
8 NES
5 Wii U
3 3DS

I never sell my games.

I have way over 1000. To many to list. I have over 250 Dreamcast games alone. More than 200 Xbox/Xbox 360 games and tons of retro games. Of course I get the bulk of these when discounted heavily or years down the line.

most of mine are in my games collection on my profile, but I don't remember if it has all my old old games (master system/mega drive). and it probably needs updated.

 I now have over 385 games. I always trade in games that I beat, except RPGs, but I haven't beaten a game in a while.
