As if the material requirements weren't difficult and challenging enough, it's hard enough to level to Meister without using up the materials for the items I actually want to craft.
It's not even political at this point since there are already clothes that are gender locked as Male/Female and even gender neutral already, that purposefully go against gender norms as novelty items in game. From a player's standpoint, is also seems like it would be more profitable for Nexon. There have been TONS of times where I wanted to try and possibly buy an item, but then disappointingly realize it's gender locked.
I personally feel it's a bit archaic for games to still gender lock marriages since same sex marriage has been legalized in many countries, or why restrictions were implemented in the first place. I've even played Asia based games, where it's not even legal, but you could marry same-sex characters. They didn't care. Why? I don't know, maybe because it's just a game? Like AKradian already mentioned, accounts aren't even gender locked, and it's pretty easy to crossdress if you did create a character unrelated to your own gender just to marry. So nothing's really stopping any guys or girls from marrying each other for fun or seriously besides inconveniencing your players, and just losing profit if they don't want to deal with them. Anyways, I doubt Maplestory would face backlash and I can only imagine positive publicity if they do in this day and age. ¯\_(ツ)_/¯
I also disagree with comments saying that doing so will only make customization less unique. Yes, there are particular faces and hair styles that are popular among the community, but Maple has gone a LONG way since Pre Big Bang era where everyone did look a like because Royals, Beauty Salon, or Perm NX didn't exist yet. Besides a lot of characters having similar hairstyles and faces (can't blame them because they're the nicer looking ones maybe done so on purpose because of Royal RNG), I find everyone's outfits pretty unique ever since Perm NX became implemented and more common.
