And how will I ever climb a mountain that high? It's going to be freaking impossible! If you fall down a vertical drop you'll have to wait ten minutes to die!
In other words, I am totally psyched!
Which is why I can't wait for the next version of the Zeppelin Mod. Mouser X has talked it's author into adjusting it so that you can change it's max height in it's config file in it's next version. So long as there aren't any other compatibility issues it should they allow us to fly sky ships around in these brave new worlds!
btw: I am very happy to report that another [WIP] Mod that I have a very personal interest in, the Pullcart Mod, is working great with the Zeppelin Mod! The pullcart mod is still very alpha and the current version has an amusing little temporary addition to it, but it seems to bring much needed functionality to the Zepplin Mod, and promises to bring more once the Furnace carts are fully working.
You can see screenshots and more info regarding this at my post [Post# 1933] in the Zeppelin thread.
