Maybe there could be a multi-game board for the series? I have category ideas for it if there was one. Full Game Trifecta: Every Stanley Parable game (not including the HL2 mod since it's just a mod). It would be Demonstration Office Ending, original 12 endings, and Ultra Deluxe Any% The Stanley Parable Quadrafecta: Every Stanley Parable game. HL2 mod 6 Endings, Demonstration Office Ending, original 12 Endings, and Ultra Deluxe Any% The Stanley Parable + The Beginner's Guide: Pretty self-explanatory. Both Stanley Parable and Beginner's Guide. The Stanley Parable 12 Endings and The Beginner's Guide Any%. I'm not sure how removing loads would work since it's across multiple games (and Ultra Deluxe is in Unity not Source) but these are some ideas for what a multi-game board might look like
