So, there are a number of people that like this concept -- me too at its most basic level -- but it just sums everything up to far too simply. It's critical that something is there to make each new location unique. If the difference is just a different looking setting and weaker enemies... then, no thanks... just give me one Arena. If each one has something specific and interesting to offer... sign me up! I'd be interested to hear ideas how to flesh out the quest line more.
