I give a listen to every suggestion I can, though it gets overwhelming. While I don't tend to obey them directly, I'm influenced/inspired by what I've read. I've been holding off adding too many items/monsters until I have some systems finalized, so that I wont have to do too much work to update existing content, but once that is done I'll be executing my own ideas at a faster pace.
I plan to enable modding in a number of ways so that passionate people can create their own content for the game and pass them around, instead of having to go through me.
