Sure, I have my digital Nintendo and PSN games listed. Do I count them as my overall collection? no, since this site nicely categorizes them into separate categories.
I have them listed here so I can keep track of which ones I have, so I can play them down the line.
This is only for my Console digital games though, I don't list my PC digital games - too many to list and they're all over the place, Steam, gog, Uplay, Epic Games. Generally I play on console so I'm not that particular on my PC games if I remember them or not. Recently been getting plenty of free games on Epic Games store, but I don't keep track of them.
