As you may guess we have soooo many ideas
Some of them i have already mentioned in one of our first talks:
- Growing plants/trees in respect to the local weather situation (rain amount, etc.)
- Animal population of different kinds with preys and predators with important stats like hunger level and of course obeying food situation from 1.
More advanced elements could be changing environment according to weapons used. Over time you will get more powerful weapons (tanks/maybe nukes) and at some level they will have some impact. At least for the local animal population and maybe on the global weather.
So you may wonder why there are tanks and nukes in a survival game There is a specific idea behind this and just be patient we are in the process creating a basic game design document to describe our ideas and the concept (once we know). Somewhen in the future we can give more details!
