I've been thinking about the biomes for this game. I'm curious about how they will be placed in the world. Will there be enough biomes to say, have an equator and two cold polar regions (I don't mean just those three biomes, I mean the layout)? Like earth. Maybe for the game, biomes are random but in this set pattern? I personally would like this. I like the idea of what biome you're in telling you roughly where you are in the world. The compass becomes actually useful for navigation. If you need a specific biome, you can figure out what direction to head. Instead of just going in a straight line and hoping to come across the biome you need.
Anyways.. just a thought.
