I just realized why I dont like Infdev.
There are no caves.
The best (almost, in my opinion) was finding awesomely big caves and exploring them, fighting off monsters while you search for ores of diamond and gold. But no. That's completely gone in Infdev. I want to be able to drop down into a cave on accident and fight off monsters while trying to escape, not digging down hoping to hit a spot of diamond or iron.
minecraft with no caves just takes a lot out of the game :'c
