It was a good experience totaling everything up. I'm sure there are folks with 10000 games on steam alone, I only have a couple dozen there.
I also added the games on the NES Mini, Genesis Mini, etc. as digital games so any Mini consoles are inflating my numbers a bit.
Right now at about 2200 physical and 1700 digital games.
I help run a local convention with a large videogame room though so it's not all stuff I bought for me.
