Chivalry & Sorcery Essence is an elegant, simplified version of the Chivalry & Sorcery game. It has everything you need to run realistic-feeling medieval fantasy at a personal level with a system which is just "crunchy" enough to appeal to me without being overwhelming. I'd love to see this approach expanded to include similarly elegant mass combat and land-holding rules - then it would really feel "complete" as a C&S ruleset.
I bought it in both print and PDF. My only criticism is that some of the art is slightly low resolution in the print version, but given the low price and the quality of the rules themselves, I couldn't bring myself to take a star off for this. Other than in the print version of the character sheet, I don't find it distracting, and I am not going to use the print version of the character sheet anyway (I'll print my own character sheets - who actually photocopies these from rulebooks anymore?).
