Old as dirt assets for a personal game project I worked on for a bit, Godless City. The only tiles I've ever really been proud of P: 

The game was conceptualized as Yume Nikki meets a turn based JRPG, with multiple factions of animal people based on the Olympic gods, no dialogue, optional combat/ways to beat the game without ever fighting, and a reputation system based on what you did out in the main world. Then Middens came out, and it was, well, very similar with the optional combat and how that affected things. And Middens is better than anything I can even dream of. tl;dr go play Middens because this game isn't gonna exist.
