On the whole, Avatar MUD is a great place to play. The mudschool is easily the best out there. Plus, whenever something may confuse a player, there is always someone willing to give pointers and advice. The Staff and players are friendly and they strive to keep the atmosphere peaceful.
Now, I know alot of the other reviewers are shaking their heads at this but let me see if I can explain what I see going on around the MUD.
Yes, at times when you ask for help you may be directed to a "help file". This is not a negative thing. Avatar has extensive help files that will explain your question far better than you'd think possible. If not there is always someone to clarify.
The language and flaming rules are not too harsh. Nor do they, imo, hinder role-playing. For those that think it does let me just say that you can be a cranky Orc WITHOUT using foul language or flaming someone over the PUBLIC channels.
The important thing to remember is that the rules aren't there to make your individual gameplay less enjoyable. They are there to make the game-play fun for the community as a whole. It's a what's best for the group thing.
Most players do not feel it necessary to be inappropriate on public channels. Most players never get into conflice with IMMs over language issues, and most importantly, most players don't want to hear you if you are rude, foul-mouthed, and derogitory.
These rules are what keep the MUD pleasent, peaceful and a great place to mud. At Avatar you can have fun, meet friends, and learn to be a self-sufficent.
