The first route and second route or so are very important to me. I go in blind, but try to get on the route of the LI I am most interested in, so sometimes I get on it, and sometimes I end up with another character, and in either case, if I really dislike the route/writing, I am much more likely to drop it. Though, this doesn't happen a lot, because I am also a completionist. Generally I play at least 2 routes, but if it doesn't get any better in the second route it goes into my backlog.
