Really!?! That's both difficult and easy.
I am now being horribly repetitive but I'm going to have to go with Barbarians of Lemuria again.
- Sword & Sorcery is a genre I enjoy. Human-centric and a bit grim and dark at times with the right amount of mysterious magic that can seriously bite you in the butt.
- It captures the genre very well for me.
- It is rules-lite. I don't have the time or energy anymore to memorize large volumes of rules anymore.
- It is adaptable. It captures the feel of S&S really well but it can also be adapted it to any action oriented genre. And it has. And with a little work of your own you can adapt it too.
