But you have no idea how it's going to be, just that you have to introduce yourself. I've actually tried it out, and I think it works pretty nicely. On Laanx the experience will likely change, but I don't foresee any difficulties. At first you will have to re-introduce yourself to everyone you already know, but once you've done that it will be smooth sailing. Why would you even want to know the name of that dwarf silently hammering his swords over there? Why would you even want to know the name of that newbie who's killing rats? Why do you want to see that guild sign floating over everyone's heads? So you can use OOC info IC? Because you keep statistics on everyone?
And when you do want to know someone's name, because you need it, or because you would like to know him?
/introduce: Just one command, one button.
Also, I foresee some good usages for Blue Way wizards. By using divination they would automatically know everyone's name and public guild. In other words, the need of introducing would be disabled from them if they have 40 in Blue Way minimum. (an example)
This isn't about "name" at all I would say. Labels are the way, as was here already several times said, to recognize same avatars of each character.
I'm really not up to keep checking description, while following murderer for example. (of course, I doubt he will introduce, so I'll have to see description of every of the race, every time I loose him from sight.)
Additionally think about logs. There should be name, otherwise, you will completely ruin storywriting from logs.
I don't know. Still, invisible labels is against my taste. Nice idea, but too much issues.
Keep current system, or put it in brackets [I think that there is already too much colors to confuse new players. But brackets, with the nice tutorial, knows everyone.]
