The game is going to be about survival in the wilderness. Basically, you will have to survive as long as possible in a harsh environment by crafting tools, gathering food, building a shelter, that sort of stuff. You have probably seen it done before in the likes of "
Minecraft", "
Terraria" or the more recent "
Don't Starve". Each of these games is unique in its own way and treats survival differently.
Minecraft is a 3D game about survival.. for about 3-4 hours.That is because in minecraft, surviving becomes very easy after a period of time.You build a farm for food, mine for ores in order to craft better equipment. You craft weapons and build walls to defend against night monsters. Dying also isn't so inconvenient, since you will always respawn next to the last bed you slept in.
