This game really is the pinacle of life simulation. The first two titles were great, but Creature 3 combined with Docking Station is the ultimate experience.
Have Norns, name them, feed them, help them learn language, breed them,... possibilities are endless.
ADN was also a huge part in the game, as you bered the norns, they have traits of both parents, and often mutations to evolve the species !
Norns are not the only apsect as you have loads of tools to manage them, experiment on them, built systems from parts found in the ship (I like the door alarm with mud cannon).
And with docking station, exchanging Norns has neevr been so easy and dramatically increases the genetic pool at your disposition.
This game is a no brainer if you already played a game in the series, but if you never played one, I'd recommend reading other reviews, and watching videos before buying. This game is really hard to get in, and understand all the subtilities, but it really is worth it after you start to discover all the different rooms and tools in the ship.
I hope you'll enjoy it as I did and still do.
Have fun with artificial life !
