I was watching a few of the videos but didn't see anything that really answers my question. Are there set entrances to caves or do they appear randomly in biomes? Are they randomly generated inside? Is there a limit to how many caves are available in our world and how many floors they contain? Spelunking was my favorite part of HM but so bummed at how short and predictable they were, so I'm curious how it all pulls together in this game. Either way, it looks really fun so far. ^^
