I used to have so much games, systems, accessory, and etc. that I had to rent storage room (10 x 5) to fill all the stuff.
I used to collect more than I play.
I sold most of the items since I really need the money and also finally realized that I will never play 90% of the games that I had.
I got rid of all of older generation games, NES, Genesis, Super Nintendo, TDUO, NeoGeo CD, NeoGeo Cart, etc.
1000's and 1000's of my life collection....gone
I do still have 86 XBOX 360 games, 5 PS3 games, 10 Wii games, 10 PS2 games, 20 PSOne games, 5 XBOX games, 5 NGC games, and about 100 PC games.
