I've had a great deal of fun with Eureka and a big pile of investigators I've made to play it more, the skill and trait system really makes a character that lives and breathes amd it's easy to throw someone together. Composure rolls are a great indicator for how a character should probably be acting, with the last adventure I played my character ended up at zero composure a lot. When it rolled into superficial damage, he ducked out. It felt like his own decision, it was awesome!
