Some stuff @Auroriax recommends. I generally like puzzles, rhythm games, and exploration games the most, but this list is pretty much a mix of everything. Enjoy!

Here are some other guidelines for this list:
- Only one or two games per creator—if there's more good stuff I link to the developer's page or related games.
- No 18+ stuff. (Some of it comes close, though, although these games list content warnings on their site pages.)

12 February 2019 update:

Now that the collection is rapidly approaching 100 items, and since what I like in games has changed since I started this collection, I'm gonna refine the requirements a bit. A game or thing will make it to the list if it is either:

• Genuinely smart: good puzzles,  crazy levels of polish, incredibly unique game mechanics.
• Genuinely funny: great jokes, cuteness, plain nonsense.
• Genuinely introspective: excellent commentary,  very interesting subjects, relaxing, achieves exactly what it set out to do (for me, at least).
