A Generation Spaceship is a massive ship, built for long-range colonization into distant worlds. When things go right, the colony makes their way to the new world - if not, it could be disasters, or it could be the backdrop of an awesome Metamorphosis Alpha-styled setting.
Layout and Environments
In order to accommodate the colonists with what they need to build a new colony, these ships are universally huge! These ships would have environmental decks to maintain ecological conditions, but for the most part, the ship would be a maze of rooms and corridors - like a dungeon... IN SPACE!!!
