What is better server WadEmu, RunWoW (based on RunUo) Mangos or Kobold?
and i need a good answer for this Not like beacuse all use mangos or kind like that
for example
Mangos is better beacuse have a lot items and options implement
or Wademu have better packet sending etc

Hmm.. Well, the best thing for you to do is to try each one, and see which one you think is better. Good luck on finding RunWoW or WadEmu though...
