In my opinion, this one (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ArYaElSiATs.html) should be remembered as great accordion music in games. I wanted more after hearing it and I found your compilation looking it up. :)
You could add A Red Apple Fell From the Sky (Accordion Version)- Gravity Rush 2, Midnight Owl- Sonic Lost World, and Feather Fiend- Donkey Kong Country Returns.
In tango there is a lot of that. Listen to Piazolla pieces or similar composers. Maybe is not the most cozy like music, but it´s accordion with an orchestral accompaniment
