I recently tried to add Sonic Dreams Collection by Arcane Kids a few weeks ago and was told it could not be added to the wiki because;
Games that are not officially licensed do not qualify for a page. For example, fan-made games that use characters without permission.
While I totally agree with the ruling, I wonder why the Bubsy 3D game has a page because it states that it is an "unlicensed Bubsy game" in the wiki text. I'm not sure if this is true, but if it is, the game shouldn't have a page.
