User blog comment:TheWarGame/Sonic Exodus - a 3D sonic fan game done right/@comment-3027069-20130424201153/@comment-25685240-20130424202457

Fan games can only be for PC, I think they chose the classic Sonic model because the guy who orginally came up with this idea likes Classic Sonic's design more than Modern Sonic's.

Oh, and only one guy is coding this, another guy came up with the idea and some parts of the level, but it's mainly one guy using the GDK engine to make this game, hence why there may only be one level unless more people come in and help code it.
