Maplestory is not dying, it is already deceased

So what would you do with it if you could get the IP?

Simplify, consolidate.

• Get rid of the cluttered fucking UI, seriously half of those things are unnecessary. Most of the standard age group is 14-25, they can figure out how to open a goddamn quest log without having a button.
  
• Get rid of potential, seriously I don't even care how many people quit over this. The idea of making your damage so dependent on this is absolutely deprived of any ethics. Id replace the revenue with things like Gachapon/boxes that give out chairs/pets. But I would also put a ticketing system where for every ticket/box you buy gives you a ticket (critical chance to get up to 5), where you can exchange them for the items in the boxes. Tickets will also drop from bosses (Bundles up to 10). Depending on the items chance I'll make the highest up to 5,000, the lowest being like, 50.
  
• Revamp all the classes, the whole concept of AOE's and hurricane skills will be dropped, or exclusive to classes with balance related to their benefit. I'd also give them gimmicks, returning to concepts like Dark Knight being very buff oriented, while Shadowers were very flow like.
  
• I'd reward having multiple classes by having discounts (including NX), increased storage (as in able to regulate all inventories on all characters), and maybe an aesthetic where you can fuse two sub classes specific clothes to create an entirely new outfit those classes can specifically wear. To even add to this further "ALL CLASS" equips, such as the smiling mask, can also give you special exclusive costumes or whatever. For the exclusives I'd put something relatively cheap in the CS, like, 400 NX to be used as fusing material for anything that came from the boxes/gachapon.
  
• Go back to the scroll system with equipment, remove the break feature, add materials to be used with the scroll that are NPCable drops, encouraging grinding outside of the "BEST EXP". This includes boss material that could be used (Zakums eye)
  
• Option of special dungeons specifically for parties, it encourages party play, doesn't create havoc trying to find a channel.
  

The biggest changes would be minimizing the class selection and focusing on balancing between them. Get rid of AOE/super buffs/passive haste/Flash jump/infinte frame moves. You're just playing a GM class at this point, there needs to be a reeling back so players take actual time to explore maps, where partying makes goddamn sense again. These would be the priorities for me. Also I would probably do a character wipe, have the IGNS who have been active at least in a year (as in ANY activity on the account) be email locked. I'd also probably allow a 'recreation' but only after an allotted amount of time. For example if you have a level 250 character, depending on the EXP ratio, I won't allow you to have access to the regenerated character (CS relations exempt) until a character reaches that level. This is to ensure a revival with no head starts or unfair leverage for players.

I'd also do more to encourage minigames such as omok, make it so you can possibly bet NX/Meso, or get a surprise reward from winning. Probably put some safeguard that affects win/loss ratios, but have a bet match up to 5 times per character. The prizes wouldn't be anything big, like unique omok pieces or something.

Those are just some things off the top of my head.
