I started writing Threadbare about 4 years ago. At the time, it was a much more traditional role playing game, and it had combat at the forefront. I put up a few hundred bucks to hire an artist (Emily Block), who did the preliminary artwork you see in the Kickstarter page and in the playtest materials.
Over the course of the intervening 4 years, I have worked on Threadbare and playtested it a lot. I've learned a lot as a game designer as well-- Threadbare was the 2nd game I ever made, after all. And over time, I realized this is not a game about harming people. It's a game about fixing and making stuff. It's about building things-- devices as well as connections between characters.
One of the "core things" covered by the initial funding goal is new, updated artwork, this time by Eric Quigley. Emily isn't available now, though she wishes the project well! So you can definitely expect new, less combat-oriented art in the final book.
