Compared to the public version, Dandies’ one includes additional clothes and customization options. Some of these could be temporarily available to the public as event or seasonal items, but Dandies have the full access to it all the year. Also Dandies have access to major releases 1-2 weeks earlier. However to keep things exclusive for patrons this version is available only as a web-release (browser only, no actual downloadables included).
The main bonus of Collectionists’/Beta version is that it handles the ‘work in progress’ state of the game. This means each major new feature is added to Beta once it’s finished. When all planned features are done and properly tested the release to Dandies’ version happens. This also means Beta might contain minor bugs uncaught through the primary testing. To compensate for this, a few more exclusive items are available on Beta only. The same as Dandies’ version, this is available only as a web-release.
