232 according to VGC. Of course that excludes that games I simply cannot get entered into its system. There are about 30-40 PC games on top of that. I'd wager i'm getting really close to 300 if not past that already. Of course are also about about 15 to 20 Atari games and a few commodore 64 games as well.
I keep these games for for several different reasons, not all aply to every game but here goes.
1) Sentimental purposes. Despite my numerous games I generally bought the game after extremely careful consideration. I don't buy many sports or quick games that would normally get discarded the next year. I often play or intend to play each game more than 60+ hours. If the game is good enough ill play them for 100s and 100s of hours (mostly the RPGs).
2) It feels wrong to sell a game I bought for $50-$70 back to a store for like $10-$20 and have them sell it used for $30-$40 or even more. If im going to offload a game I will never play again and have no collection/nostolgia purposes for keeping it, then i'm likely to give it away to a relative or one of my friends kids.
3) I'm also obsessive collector for series that I like. I own many different copies (on different consoles) of the same final fantasy game for instance.
