I like the idea of dirt instead of rains, but the rest is kinda problematic...
I think that big rocks that could squash you \\ trap you in a cave would really suck. Hard things in games are challenging, but when you walk around and get squashed by a giant rock that fell from the cieling it\'s not challenging - it\'s aggrevating.
The small rocks might be ok, but think about it. The cave is huge, bigger than half of the PS planet (according to one of the maps in the PS world thread). Even a small pebble that will fall from the cieling to the bottom of the cave will create quite a nasty hole - atleast according to our laws of physics. Power = Mass times Velocity or something, and as the pebble will fall longer, it\'s velocity will increase... Ouch.
I don\'t think that ore should fall from the cieling either, it\'s too easy. Ore and other valuable things should be mined in specific places. You can\'t just dig wherever you want and expect to find iron, oil, or whatever, right? These things are located in certain places, and that\'s why they\'re valuable.
And since valuable means hard to get, having ore falling off of the roof will render it invaluable. Even if it\'ll be rare.
You should be able to get ore only by mining. Unless, of course, you\'re a thief, or a merchant, or your axe happened to fall on a merchant, chopped his head off, and your hand accidently took everything he had...
