I have 100 GB of games because i keep all data for the next version not only saves, then i have another <50 GB of other downloaded stuff + screenshots from games
I definitely have at least 400-500 gb's worth of hgames, I've been meaning to go through them to delete abandoned and any older version of a game i missed
I used to keep only a handful of games but after so many file host shut downs and with the cost of HDDs being so low I always save the highest quality versions indefinitely.
Currently have nothing on my drive, because I don't replay the games as soon as I finished playing them and if a new update comes out, I still have to download that, so don't really see the point of wasting storage space
A good amount over 100+ Gigs. I've been meaning on clearing out completed games or those that I've lost interest in. I'll get to it before my procrastination tendencies get to me again.
