Honestly,
I cannot agree with a dedicated board for
The Legendary Starfy either. I expect an almost absolute chance of neglection of a Starfy subforum here simply due to the obscurity and lack of recent official Starfy news and discussion.
Very little recent news about Starfy is arriving. Most of the news are just about the fandom. There only been one recent occurrence of official Starfy news (his appearance in Super Mario Maker). The only recent new discussion was a video on YouTube explaining why a 3DS Starfy game would be a good idea.
Also, another separate forum dedicated to The Legendary Starfy is already present.
If I were to have had think of this more critically, then there would be more factors to consider. If many people on these forums were fans of both Nintendo and non-Nintendo games (provided that they create threads about Nintendo and non-Nintendo games), then that could merit a justification for making a Nintendo subforum.
For example, we can take a look at the Video Game Memorabilia Museum Forums. If there are lots of new Mario and Legend of Zelda merchandise to be tracked down, then separate boards should be made.
If a new generation of KRR staff is going to run the site, these people must care much moe about Kirby.
