This is an interesting challenge, and one that coincides with what is happening to date in the gaming industry. It's much harder, I think, finding that kind of diversity in gaming unless you drop all AAA titles and focus strictly on indie titles. Even then, the pool is quite tiny.

This statement is, of course, coming from someone who doesn't have nearly the same amount of literary prowess as you do.

With all of that being said, I hope that you find the challenge to be invigorating and enlightening. I'm not sure what the purpose of reading from various authors will serve (I assume to gather more varied points of view or writing styles?) but you'll have to let us know if you notice anything significant as you progress onward.

Good luck!
