Well, me has now figured better plot-line and stuff for this! Ok, let's spill it out now:
In Earth-time, the year is around 2148, set in a post-apocalyptic world lays in the hands of the players to reshape and destroy. Few survivors still thrive on this human-owned world, yet there is still much to survive through or destroy. It's up to the player at this point to decide how to deal with the characters they and others make, by either allowing them to somehow live, or wiping them off the face of this forgotten planet. Supplies from a nearby colony are dropped in every week or so, but they don't have the right resources to try and save those remaining nor do they wield the proper equipment at their disposal.
As a short note: factions will be involved, but there WILL be a rule about the size and strength of them. For one, no going, "OLOLOL MY GROUP HAZ UH MILLIONZ STRONG!" or "I own the whole planet! HA HA HA!" You'll be reduced to a minimum of 25 strong at the start IF you decide to make one, and it can become maxed out to atleast 75-100 people.
As another note: You'll have the power to create different species of mosterous creatures, but there will be a couple of rules on this to. One, you can't over-power them (obviously,

) and two, you can't make millions to billions and say they rule every part of the planet. That's a big no go and a boot up the arse.
One more short note: Yes... you, and I mean the player, controls weather, atmosphere, creatures and some anonymous objects from space to f**k up other people's characters. But no way, and I mean, NO WAY will you be allowed to start up something on another world... at all. Unless, of course, you decide to make a character for the nearby colony's ship hovering over this massive planet...
