There are a few curators that list very information stuff. I will just list all of mine.

1. Games That Hate You
2. 3rd Party DRM Ark
3. Games at risk of removal
4. SteamDB
5. Graphics Engine
6. 4 Player Co-op Games
7. Games for Lovers

How about a game that is not on Steam after your show off just to flex that the thing is in fact still a PC and can run more games then just games from Steam?
