I think a "normal" target/walmart could be fun, but if you explore around in the staff-only rooms, you'll find a hatch that leads into a basement, and it has cages and stuff, and you find out that while they were open, they were capturing people from the store, and keeping them in the basement. When it was abandoned, no-one was let out, so you find stuff like skeletons in prison cells, diaries, insane scrawling on the walls, pleading for someone to come for them. But you are too late. The only thing you can do, is try to unravel what truly happened here.

A long abandoned K-Mart sitting near a still-busy street, rain/snow pouring down its roof as the faded signs still stand and doors sealed off. Inside it's rather dark and overgrown and open from areas that the roof had fallen in and gave way to nature to crawl into into. All around inside are indents of shelves, TV's, counters, and the sort, clearly showing what once lied there, now only remains are the pillars and some forgotten shelves and items. The staff-only rooms are moldy too, though their sealed nature has led them to still have more of a hint of their former selves. Obviously, rouge's have graffiti-ed inside and out, as many forgotten places and even places-in-use are.

A K-Mart would be fun, that's also nostalgic AF.
