If you count DOSBox as emulation (what it definitely is - unlike WINE it actually emulates an x86 PC and peripherals):

• The Settlers 2: This is a timeless classic. The graphics are 2D, but they still look OK today.
• Albion: A Science Fiction and Fantasy RPG (yes, it has both, and that’a a key point of the story). The gameplay itself isn’t that great, but the lore, story and the graphics are amazing.

I’ve played both on the Deck, and they both work great. (Btw: I did not use Settlers 2 as an example for my DOSBox setup guide by chance. I picked it because it is an amazing game and still fun nowadays.)
