KMST 1.2.482 Zero

Calling it a second IGN was definitely my mistake.

Let's define a character IGN as the name of the entinty which holds all the character-related information inside the database and serves as the keyfield for interaction between the character and the rest of the game processes. That's what makes it so hard to deal with an IGN.

Now lets say this name for Beta is nothing more than an aesthetic tittle which doesn't have any function in game, all the contrary to that of an IGN. No whispering, no adding to BL, no adding to parties, no name tag on items created in any way, just a tittle for the looks like with a pet, where its name doesn't hold any value in the processes that go behind to carry out its functions.

Anyway, I'm done with this. It's not like this is a must-add feature, I just don't get why peopel keep saying it would blow up the game.

In that case, you are cementing the fact that Alpha is the character, and Beta is just a glorified summon/pet/familiar/android. If some person were to actually prefer to play the Beta as his main Zero, and only tag Alpha as needed, the name under the active character would not be the name by which you add him to party or whisper to him or w/e.
At least the way Nexon has it, the name stays on the character that's currently being controlled by the player.
