I know that a lot of these have been stated before, but hey, what harm could one more listing do?
-Just because you can write a crossover doesn’t mean you should. (http://www.fanfiction.net/u/843106/
-Rule of thumb: If you insist that your character isn’t a Mary Sue, chances are s/he is.
-The name of the town is Quahog. Not Colhog, Kohog, Koerhåg, or anything else.
-Peter’s wife is named Lois, not Louis or Louise.
LEGEND OF MANA
-Believe it or not, the Jumi story arc isn’t the only one in the game. Why not write about the Dragon or Faerie arcs, or one of the minor arcs, or even one of the stand-alone events? That would be just as interesting as a Jumi fic, if not more so, if only because it‘s not oversaturated.
-As much as I love HIVE Five fics, the other HIVE students need love too! I’d love to see something about Angel or XL Terrestrial, or about why Private HIVE left the Five between “Mother Mae-Eye” and “Lightspeed,” for example.
-If you write a Season 6 fic and feature any villains from the first five seasons other than Slade, Blackfire, Brother Blood, Red X, or Dr. Light, you should probably have an explanation of how they got unfrozen. Believe me, I thought that the whole “freezing the villains” thing was kind of lame (kind of really lame, in fact), but still, I just feel that an explanation is needed if they’re unfrozen.
