Maps? Yes Sir.
Tilesets? No thank you.
I myself have preferred tilesets. I usually opt for Dark Forest, Scrubs or Evergreen. Tilesets are purely aesthetic, so I don't really see any point in this.
It's not forced, mate. It's just another option, and if you don't want it, there's no need to use it, but those who do want it can use it. Yes, tilesets are just to look good, but they can completely change the feel of the map, especially when combined with random starting positions and/or random maps. Plus, it's LITERALLY a two line fix (or at least in MG, and can't be too different).
