I'm honestly not holding onto as many games this gen, due to how quickly most of them go down in price. Cheaper to buy it, play it, then trade or sell it, and if i feel like it, rebuy it in the future.

Edit: I see many have included their Virtual Console titles. Problem is for me, most of my over 100 VC titles came from my Wii, so dunno if these count in any way. New for sure are Earthbound, Earthbound Beginnings, Dr. Kawashima Brain Training, Advance Wars and Fire Emblem, but I don't know about all the others.

kinda sad but I only own 4 physical retail games.

Xbox One

Sunset Overdrive
Watch Dogs
Master Chief collection
Middle Earth

It's like me. I only own 4 physical games, but I've had my PS4 for a month now. Still, you start somewhere.

My collection is pretty mediocre, games here in my country are expensive, so i just have a small handfull of games. :)

Edit: I forgot about my Indie and virtual console collection. :p

15 VC games on 3DS (Including all the classic Zelda games on NES,GB and GBC, Super Mario bros 3, and a Game gear game called Defender of the Oasis that i got for some reason)

8 VC games on WiiU (Including The Legend of Zelda: The minish Cap, Mario Kart DS, Paper Mario 64 and Earthbound)
