I like this. I also hope that notch makes it so that the deeper you go, the hotter it gets. This whole temperature thing, plus hopefully hunger and sleep will make minecraft an incredibly deep survival experience.
I would love to see more realism added to the game in terms of making the environment more deadly.
Just off the top of my head :smile.gif: (+wish-list lol)
Freezing Temps -Hypothermia
Hot Temps - Dehydration
slippery snow blocks (sides of mountains)
some more realistic properties of gravity and some blocks (floating blocks fall)
cut down trees (not one block at a time, if the trunk is cut the whole tree falls apart (as if made of current sand or something like cactus)
plenty more mobs, migration, camps, caves, niches etc
Shields for players and some mobs
holdable torches (light those around you)
