Those are created by our publisher so unfortunately I can't say for sure which bundles they'll want to make, but I don't think one like this currently exists on Steam.
Viewing post in KR Urban Modern Interiors Tileset for RPGs comments
I was trying to hunt down a Urban Modern Interior and Exterior bundle but from other discussions I've had on reddit, I know there has been some talk and interest in other bundles to possibly purchase tilesets needed for specific scenes (I'm surprised no one came to you guys before).
I'll probably need other tilesets as I go (I have a sewer stage planned but I'm not that far in development) but a Urban Modern Interior and Exterior should be enough for me. Hell I would probably buy it if it came with the sewer but don't allow me to bundle your products, lol.
On a side note, thank you guys again for the discussion, even if the answer is later unfavorable.
