At least we hope it'd be. We have the biggest amount of fanfics but archiveofourown and tumblr MTG fics are twice as popular.
Yup, and I'm not truly surprised by that. Most fanfics tend to use canon characters above all (somebody said AU?) and main characters are the foremost attraction in the current MtG lore as well. The second attraction is usually the setting, and we M:EMbers ditch more or less half of it by just tiptoeing at the outskirts of canon planes and having most of our fan in fanmade planes. Thus our fics require more commitment than common AUs, which explains the lower popularity.
Also, do we really have the biggest amount of fics? What meter are you using for this? Tumblr fics must be hell to keep track of
and having several unarchived fics doesn't do us any favors I guessAlso pt.2: how do you measure popularity? We certainly have no way to compare kudos
PS: Ravnica is an awesome place for setting both over-the-top and dark cloak and dagger campaigns in, my GMing efforts have been drawn to it as well.
