In addition to the Creatures 4 game in the pack, the Collector's Edition lets you (re)discover the previous episodes of Creatures so you can have a clearer picture of the story and what the series has to offer. The three previous works are included in the collector's version!
In addition to the 4 games of the Creatures saga, there is also a wallet pre-filled with Golden Eggs so you can discover all of the possibilities this virtual money has to offer. You will thus be able to visit the Creatures 4 virtual store, buy your things and give your Norns all of the necessary resources so they can live on Sphericus (plants, critters, backgrounds, attractions, coin machines?).

There is also a limited edition figurine and an exclusive genome so you can start the game with a unique Norn!
