hell, Im in this situation myself, I think my games collection is at if not over 1k games. 744 on steam and then at lease a few hundred across the other platforms (EA, Battlenet, EPIC, etc....). I am actually thinking of doing an alphabetical run through of my games and uploading the play through to youtube...but here is the sad state of my current games folders.
All the drives with Red around them are NOTHING but games

The drives currently total 18TB of space and of that I am using approximately 11.6TBs and im still not fully installed
