this is a very cool concept but i feel like it lacks something else to do
staring at plants doesn't exactly give much entertainment (to me at least)
the teamwork pictures theepicman posted really reminded me of oc_harvest though
if anyone has played obsidian conflict (hl2 coop mod) then they probably remenber that map
if not, here's a
link to a wiki page on it
i think that making something similar to that would be very interesting in blockland, having cooperation and stuff going on, buying items to improve the farm, etc
of course, there could always be people that mess stuff up, but you really can't escape that, you have to bear with it
but i think it'd be fun!
