i guess i'll partially bumnp 
I voted for a giant tre, with items, not user generated stuff, graphics can only help, and that sound is needed. i also voted for the game to be free
i want to do a giant tree because i think it can be a lot of fun. then adding items would help.
user generated content would be hard, be it maps or items, and i might allow it if everyone required - maybe an update
i would like nice graphics but it seems that most don;t care too much
i want the game to be free because i think it will increase number of players
