Methinks the number of games in a single series does not justify the size of a wiki at all! For example, there had been five official games in the Star Fox series, two cancelled games (which one has been fully leaked into the internet), with a rumour a sixth game in currently in the works, and the series has a big fandom, loads of merchandise, and additionally three characters, with several related elements, in
Super Smash Bros. Brawl, and one of the characters is a veteran since the very first game. However, apparently,
the Star Fox wiki on Wikia seems to have a lot less articles than
the Wikia wiki about the Mother series, which only has three games by far, each one almost a decade apart!
Just a thought to think about when regarding establishing wikis based on certain "minor" series.
Saying that the lack of availablity of certain game titles outside Japan would hinder a wiki's database of information is utterly not excusable! I mean, seriously, the original six Final Fantasy games weren't all released in the west, and yet people managed to find out about them anyway during the early days even before
Final Fantasy VII was ever first released! I also notice Fire Emblem's fanbase seems to know an awful lot about the earlier games, which weren't released outside Japan either! Apparently, a lot of people were aware of the series even before Nintendo included Marth and Roy in
Super Smash Bros. Melee!
By the way, I still think series like the ever-forgotten
StarTropics, Nintendo's newly-owned
Glory of Heracles, and Nintendo's
many one-timers from the Nintendo Entertainment System days, should all have their own wikis! I believe we can include the many one-timers in a collective wiki, and call it like the "Nintendo 8-Bit Generation Wiki" or something...
Oh, and Hotchmoney, Nintendogs games is considered to be part of the Touch! Generations franchise. It cannot have its own wiki.
