I exactly agree with you. I'm not a kid anymore, I do have a disposable income unlike when I was younger. I have, let's see, 155 ONE HUNDRED and FIFTY FIVE games installed in Steam right now. I don't use a personal credit card on Steam, or the Internet in general but that's another matter, so what I do is go to a local store and buy one of those "disposable" ones. You gotta use 'em all up as best you can. Believe me: I have ton's of Indie game that I haven't even touched. I have big name games I haven't touched! Like Batman: Arkham Asylum, Battlefield: Bad Company 2, Call of Duty Black Ops, MW, MW2, and World at War, Cryostasis, Dead Island, Dungeons and Dragons: Daggerdale, Hard Reset, Medal of Honor (the new one), Red Faction: Guerrilla, STALKER: Call of Pripyat, Singularity - and all of those are just the big names, because I buy those disposable credit cards I'm always filling in the last $5-$10 with Indie games. That's the reason I'm up to 155 games.
So, it's well established that while I might want to play Far Cry 3 I, in fact, have plenty to play that I haven't touched in place of it. My backlog is so shameful that I keep telling myself I'm not allowed to buy any more games until I play what I have. Then I OCD buy more games anyway. Ironic, when I was a kid I had all the time to play games but no money to buy them, now I have too much money, apparently, and not enough time to keep up playing-wise with my buying rate.
