All implicating fire_emblem

I've got them all set up to go, but before I put them through, is there anything in fire_emblem that needs to be moved to a separate fire_emblem_i tag? Like with other series umbrella tags that use the plain-name tag of the first game.

There's rekka no ken that was released as just fire emblem internationally but the 5 most populous sub-tags add up to ~85% of the current fire_emblem count so you're probably good to go.

fire_emblem_mystery_of_the_emblem is an enhanced remake of the first Fire Emblem with a sequel added on so there's no need for a fire_emblem_i tag.

Okay, done.
