Gardener fleet/ark ship/no FTL

It's 2250, and you're on a rotating habitat or O'Neal cylinder the size of the United States. Biotechnology, humaniod robots, ai, virtual reality, bci, and cyber ware are all mature technologies. You can be any race, gender, machine or combination of your choice. The fleet had many ships of varying sizes full of different styles of colony, such as medieval or Amish or virtual reality or homesteading. Some ships/habitats are nature reserves for current and extinct life, some are massive cities and everything in-between. You can be any age as immortality was invented in 2030, and technology allows for time dilation or frame jacking. You can try to become captain, get a homestead, join any group of people you can think of, or anything in between. You can start as an established character owning land or someone new who woke from cryo sleep or a child on a ship that lives as the Azteca did until adulthood when they learn of the other ships and technology. The fleet is reaching another star system within a year along the path to Andromeda, where some people will stay, and some will continue on to the next star and some will go elsewhere, like Earth. The ships will stop at a gas giant with moons first to gather supplies and make new ships before settling any planets in the system. The planetary system can be chosen or rolled by the ai. Enjoy your new life and journey, and please share your stories.
