I foresee getting stabbed by the famous Cockspear and getting crushtrhoughed by the Arsehammer 2000.
It would not be special if anyone could "Engrave" weapons. Sure, a sword might be considered a higher value if a "Famous" player engraves it. Although, what is the point? They can sell it for more gold in the marketplace? Do they need anymore gold?
I am not against having name for weapons or just placing your own name in it. Although, I think it should be based around either a HUGE amount of kills or time used with the weapon. While the auction hall idea would kill a lot of the gold in the community, it would also place more in the hands of those who own the weapon.
Engraving
Because when you are ruining this game for newbs, you might as well look cool while doing it.
