I always wanted to make a game where you go against another human, and try to hack into each other's systems; but with pretty graphics and some "physical" game world, where your agents could be autonomous or remote-controlled bots. So there's a bit of combat / tactics; "hacking" something could require solving a very short minigame (2048, tetris, hangman, think WarioWare[2]); you could dump a fallen enemy bot's memory to recover their programming and look for a weakness; deploy RF jammer to make enemy bots in the area revert to auto-pilot; etc. You get to make your own designs, setup perimeter defenses, maybe a little bit like Factorio meets Robot Wars, with scripting in Forth/Scheme/Lua.
