IMO, it's natural that people will recommend what they know and like. I'm trying to broaden my scope, in part, so that I don't fall in the habit of recommending pet systems over and over again; instead, I want to better address the needs of the petitioner. (It's a work in progress.) I personally feel a bit silly recommending ICRPG a lot lately - it's not really one of my pet systems - but there have been a number of threads where it meets the basic criteria presented by the petitioner. In this case, sci-fi/generic games with free quick starts.
