What’s your jank tolerance like? If “moderate to high”, Mount & Blade or Outward might scratch the itch for you. If you’re up for post apocalyptic ronin shenanigans with more of a strategy feel, Kenshi might be enjoyable. Technically, Noita is an open-world fantasy game. It’s really hard (I’m really bad), but I love it nonetheless.
Going more mainstream there’s shedloads of mods for classics like Morrowind, Oblivion, and Skyrim to update graphics, mechanics, or just new content. Witcher 3 is still really good, too.
