For starters a Remake.
It would have a real time combat element that is the default, but you could choose classic turn-based style too. It would be fully 3D and is zoomed out isometric by default but can be zoomed all the way in to over the shoulder. I would also add co-op that is drop in drop out, allowing the game to be played like a an old school cooperative dungeon crawler/twin stick shooter akin to Smash TV.
I would heavily expand on the towns of the game adding new characters new quests branching dialogue that impacts the overarching story. There would also be randomized events that Tim Cain has brought up, a much more interactive and reactive wasteland, where if you take out a bandit camp that causes more factions to grow in influence, think the Nemesis System from Shadows of Mordor but for factions in lieu of individual characters.
There simply has to be a non-lethal approach to the entire game, and an achievement for pulling it off. The original was way too reliant on Agility stat and shooting, so there needs to be more checks for Intelligence and Charisma.
