Kickstarter pledge rate is pretty incredible. I think the documentary will probably happen (AWESOME!!) Might even need to think about what comes after that? How about the whole wildlife on planets idea? Maybe as "new planet types" of jungle, savannah, gasbag, and biotic ocean worlds? (I'm thinking huuuge oceanic lily pads as islands with the last one!) Last 12 hours might be a bit late to announce something like that... but I think another goal could just be attained!
I guess What if it goes to 2 billion dollars though Then you'll feel silly for not having asked for more stretch goals
Well you can always throw money into polishing and balancing the whole thing without bloating any "features" list. I woulnd't really mind missing on the more extraneous features currently scheduled either if it meant a better base game.
Stretch goal 7: Easter egg where all sound effects are done by John Lowrie using only his voice, a la this.
You need to stop using things where they don't work and have nothing to bring the statement on. Forcing is bad.
