This is all guesstimates.
Physical copies:
A dozen gameboy titles, I got rid of my original gameboy but still have a gameboy color.
Another dozen gameboy advanced games. I have a blue gameboy advanced sp still.
12 or so wii titles. I guess I really like getting my collection to around 12.
9 Nintendo ds/3ds games for my blue 2ds.
A box full of 30 or so cds/dvd games like warcraft 3 plus expansions, assasin's creed, dragon age originals, various heroes of might and magic games, civ4, mechwarrior. Tons more. Alas despite all this I can't find my civ2 copies.
I got rid of my Nintendo 64 and 10 games a few years back but regret it now.
Digital copies:
Gog 118 games. Exact just checked.
Steam 634 games. Exact just checked.
EA Origin something like 20 games, all from humble bundle or freebies. Only game I bought from origin was Dragon Age Inquisition.
Twitch 35 games. I have twitch prime and they give away a ton of free stuff.
Of course many of those are duplicates since gog syncs with your steam library. I bought Dragon Age Origins physical copy and I have the ultimate edition off gog. Same with mass effect 2, I have a version in origin, on steam and physical copy. I think they were all part of bundles or something.
