I'm starting to think that IG should change the way the map handles new biomes. If an "under_development" flag could be added to the location metadata, then the terrain and its contents could be re-generated each time the player enters, just as they are the first time. (Or maybe this tag just goes with the biome)

This would allow a biome to be developed and released in pieces. As soon as new critters, plants, poi or whatever are added and released in an update they appear. Players can comment, find bugs and so on as the new biome is developed in whatever sized chunks the devs think works best.

You couldn't build in a biome that's under development, and that might even preclude lighting a campfire. (Alternately, any changes you did make would be wiped out when you returned.)

This is a process known as Rapid Evolutionary Development, and it is extremely efficient. We want that, right?
