Hello.   I'm curious about the contents of the early access.  Like   how many backgrounds can we play with,   which characters  are romanceable  right now and how many endings can we get?   

The only backgrounds and romance routes not included are the 3 secret backgrounds (more than you appear in the CC), and the kickstarter stretch goal romances for Leala, Kade, and Greer. The endings possible will depend on what choices you make, but there are a LOT.
