Goshi-Dan's Arcade
From Mario Fan Games Galaxy Wiki
Goshi-Dan's Arcade is Kitsune Yamato's website based around his RyuFox series. It is currently hosted on Taloncrossing, just like MFGG.
Its forums, Kannagi Stadium are largely made up of MFGGers, many of whom have left MFGG for various reasons. In fact it is often considered an MFGG 2 because of this. KS is nowhere near as active as MFGG however, partly due to the fact MFGG has 4000+ more members and a further 3000 from the main site. Apparently a new version of the forum opened in September 2010, but it's still not very active.
