Very interesting. The list of proposed features is very very long: the game looks interesting-but-still-barebones right now, I'll wait and see if any new stuff gets added and/or for further polish before picking it up. Despite all the unlocks and stuff added to the game the super-solid core class gameplay of TF2 is still what makes it so good, it's going to be very difficult to keep that intact while adding a load of other stuff into the mix, so that's lowering my expectations. If they pull that off though it should be a lot of fun
