To be honest, I'm not really sure what I want to play the most. Something new, something different. It is a poor answer to give such a question, I know, but it is a less whiny one than my kneejerk response.
Thinking about the question some more, there's a lot that could be said. However, for the sake of being somewhat brief, I'll say that I am interested in the Super Robot Wars mush. It seems like a good place, but at the same time, I'm dying to know what is wrong with it.
I really dislike world of darkness, but that's what I've played the most of, unfortunately.
@Bobotron I like some of your ideas. Particularly, allowing players to have their plots run on a larger scale, or allowing them to have that cool story or mcguffin that they want. This is the sort of kudos that means more than a brief, fuzzy feeling one might get from reading a +recc. Coming off of some bitter experiences on mushes, I can honestly say that gratitude from staff could not mean less to me. A staff member's appreciation cannot be eaten, nor can it be spent. It would have been really cool to have a meaningful reward if you've legitimately earned one through contributing to the mush.
