That's an excellent addition to the game but there's a lot more that could be done to bring it up to modern usability standards and more importantly, to fuel more content for the game not just more items. What if anyone could write new campaigns like Unfinished Business?
I think this game, Project Zomboid, is a nice demonstration of how fluid and interactive an isometric world today can be.
