So I had an idea for an open world post-apocalyptic game (very original I know.)
So it was sort of like a human’s vs creatures mmorpg type game. Everyone will spawn in the same level and you can choose to be either a human or a creature. From here you start on your respected island to learn the basics of how to survive and thrive as your respected species.
Both species will have their own base stats and skill tree type things. For example, you will start off a basic human. Form here you can choose to specialize in the sciences, engineering or just basic life skills. For the creatures it could be you specialize in destroying human built objects, taking on humans in battle or adapting to the environment around you. Granted you could choose not to limit your tree and build a basic knowledge of each.
The humans wouldn’t be able to attack humans and creatures wouldn’t be able to attack creatures so there has to be some form of teamwork involved, in saying that if someone’s being mauled to death outside your hidden base you still aren’t required to open the door, but it would be nice.
Humans can create factions to fight off the hordes of creatures with their friends, find somewhere on the map to try and rebuild and survive. Creatures are there for the sole purpose that they like the broken world they live in and want to make sure it stays that way so they destroy and slaughter everything other than their own.
Humans will start off being more productive during the day but can adapt to be more productive at night creatures will be the opposite. Granted Humans will always be more productive during the day and creatures during the night.
If you have ever played PlanetSide2 that is the type of map I envision but there will be a main island for humans to go back to grind and resub (to a certain level) and creatures to do the same, but the base of the game is on a big open map with the humans and creatures fighting for territory. Basically a never ending war over land.
Creatures are the hard part making their skill trees and such so it’s even against the humans, pretty much anything a human can do there’s a creature counter to it and vice versa. Humans are easy because we just take skills and the stuff we already know about life.
