The bulk update request #12311 is pending approval.
remove alias super_mario_bros_2 (0) -> mario_bros (45957)
remove alias super_mario_bros_3 (0) -> mario_bros (45957)
remove alias new_super_mario_bros (0) -> mario_bros (45957)
remove alias super_paper_mario (0) -> paper_mario (4026)
Reason: Instead of having these aliased to the main mario_bros tag, have them aliased to the tags that actually refer to each title.
(See: super_mario_bros._2, super_mario_bros._3, new_super_mario_bros.)
super_mario_bros. is trickier to do, since it can be easily mistaken as referring to the series as a whole, so it's probably better to leave super_mario_bros._(nes) for that one, to avoid misuse.
super_paper_mario is currently voided, but mimi_(paper_mario) alone shows that there are enough posts to justify having it.
