Here are rough approximations of what I own:
PC physical - 500
PC digital - 3,000
I remember about a dozen of them.....
Wow...not to be offensive but I must ask how many of those are free or were at the time you got them?:)
Most of the digital games were free or just a couple bucks, thankfully. Wish I could say the same thing for all the physical boxes and consoles over the years though!
But I look at it this way, when in factor in all of the free iOS games I download, I probably average a buck for every game I've ever bought. ;)
