Man, I really want to see the continuation of this.
Maybe there could be some "fortuitous" encounters ; ) or maybe dangerous situations you can opt out of like secret tombs that give the chance to aquire something if you solve a riddle, make the right choices or solve a puzzle; you could get some martial arts, artifacts, or a simple upgrade to your atributes.
It's just a sugestion, what you have done to this point is really cool and I would love to see what it leads to.
