Good list. I’ve played about half of those, and most of the rest are on my wishlist. Now my wishlist is a little longer.

Eh, I’ve had pretty good luck with Verified titles. It’s not perfect, but generally speaking:

• verified - no concerns about compat
• playable - check reasons, and maybe protondb if there’s anything concerning
• unsupported/unknown - check protondb

ProtonDB also isn’t perfect, and there are plenty of “gold” and “platinum” titles that I’ve had (small) issues with.
