It’s not turn-based but there is actually a game that is 100% this.
It’s called Kingsway, and it’s an active-time-battle roguelite. And it’s designed to look AND PLAY like windows 95. And I don’t mean it plays like a windows 95 game, I mean it plays like the operating system itself. Window management is a key part of the game! Often you have to juggle many windows and pop-ups to avoid getting hit or curses or whatever.
Like, when they cast a curse on you, it pops up as a small dialog box, often behind the main window, and you have only a few seconds to click AVOID to it.
The game doesn’t pause when you do inventory management, and you often have to manage a lot of bags at once. That’s hard to do in real-time, since each one is a separate window. The game uses the Windows 95 UI as part of the difficulty!
It’s a lot of fun and I highly recommend trying it out. Currently 10$ on steam, often drops down to like 5$ when there’s a sale. Check it out.
