Currently, once you've got a stable group that is adapted to the environment, the game can become somewhat repetitive. To remedy that, it would be cool if there was also a system of intelligence, whereby a certain average group intelligence unlocks a part of a tech tree. To actually use the tools and structures in the tech tree, you would need to set certain creatures aside to research a certain aspect of the tech tree, with their individual intellect dictating how long it would take to do so. It would also be cool if the things in the tech tree after a certain amount of time are forgotten, unless an effort is made to preserve that part of the tech tree, such as building a library structure, or having certain individuals teach others about that part of the tech tree. Ideally, the tech tree would have structures, with several tiers each adapted to an environment. There would also be clothing, with different tiers adapted to different environments. There would also be weapons for hunting. The last thing would be a cooking system, which increases the overall food.

Being able to create large, custom worlds would be cool. This would work, with the player having access to a "world builder mode", whereby the player has a clean empty environemnt to play with, being able to decide the elevation, biomes and location of resources such as berry plants. This would allow for large custom worlds to be built, which could be designed by any one individual, and possibly shared to provide others with a new and original world to play in.
