Moonlighter seems like it would satisfy that old-school adventure craving.
Moonlighter is a role-playing game with “rogue-lite” elements. It follows Will, an adventurous shopkeeper who secretly dreams of becoming a hero. During an archeological excavation, a set of “Gates” were discovered in Rynoka, a small commercial village. People quickly realized that these ancient passages lead to different realms and dimensions. The portals provide brave and reckless adventurers with treasures beyond measure.
