None - all are multi-platform.

Deep Down Dungeons, Final Fantasy VI, Final Fantasy VII, Quest of Dungeons and Tyrant’s Blessing are turb-based RPGs, and Tyrant’s Blessing specifically is a tactical RPG.

About the tool, thanks. I’ll keep it in mind.

About Heroic, it allows installing several versions of a few forks of Wine, Proton and Proton-GE included, and it’s installed on a folder specific from Heroic, instead of installing on the whole system.

Alternatively, or perhaps even concurrently, you can have a Proton instance without having Steam installed. Dunno how it works on Lutris, but besides being able to install Proton manually, you should also be able to install a few different versions of it through Heroic too. Dunno other means for that but probably are.
