Featured Worlds, are worlds which have been deemed exemplary in the context of what ZZT has to offer. Often these worlds show a higher quality than their peers, and have been given their place in the spotlight here.
Originally, the ZZT community awarded worlds "Game of the Month" and "Classic Game of the Month" designation, for the best worlds released in a given month, or notable worlds released at any time. These awards eventually stopped, and were later revived in spirit with "Featured Games" and "MadTom's Pick" awards. The former replacing CGotM, and the latter replacing GoTM.
Worlds which received any of these awards have been merged into the Featured Worlds list, typically accompanied by a review and short description of the world.
On the Museum of ZZT, "Featured World" status is given to worlds not just of high quality, but also of considerable interest to those looking to see what ZZT offers.
