I have played avatar for only a little over 3 years. I am a Lady x5, a player and not an immortal. I still see AVATAR as the best mud around. Is everyone friendly 24/7? No, but the same is the case in real life. Is AVATAR ever changing, ever growing? Yes, and that is one of the things I love about it. New areas replace old, new challenges, new gear to find. Older areas are revamped to bring them more in line with the game. Is it frustrating the first time you play a well known area and it's a bit different? Yes, but ahhh the challenge. I have never played on another mud where the immortal staff cared as much as the do on AVATAR. Do they always agree with the players? No. Should they? No, for they are human and different from each of us.
Is our description perfect? No, it was written by humans. We are not mostly stock. I have entered area building contests myself and seen player areas implemented. I have watched favorite "stock" areas be replaced by new ones. And most of the time, the new ones are better and better.
So give a shot, come and play, I think you just might consider staying. And I hope you do.
