A cyberpunk Red Wall. Not a bad idea. Not very true to form either. Which I like. Mine would be in the same vein. I'd probably make one of those isometric CRPGs set in a completely alien world. Probably similar to Planescape, but without all the complicated mysticism of other dimensions and whatnot. I want something that is just simply an alien planet. No alternate earth. No human rule. Just aliens. Possibly humanoids. But not actual humans

Alien locals. Alien weapons. Alien powers and abilities. Lots of different cultures and regional differences so there isn't any stigma of all Zerg are like this, or all Protheon are like that etc. Might even allow for space faring. But not beyond the solar system. I don't want mass effect. I just want to deeply explore alien cultures and save a civilization or two that isn't dependent on a human population

Now I am absolutely enamored with combat systems like XCOM: EU/EW and Divinity: OS, and now Wasteland 2. So I'd probably do combat like that, it really gives me my tactical rpg fix that games like Final Fantasy Tactics just doesn't scratch for me
