The first thing to say is if you don't have patience, willingness to learn, and time to understand the in depth way this MOO works then it might now be for you. But since I started this MOO nearly a year ago I haven't stopped playing and don't intend to despite the learning curve.
If you are looking for in depth RP with heavy themes, challenges, and a great community then this is for you.
If you are looking for hack and slack, don't like much roleplay, and want to get gear and be elite, then this is not for you.
Sindome is about a single character surviving in its challenging world using an intuitive system, but you can forget about how all the coding, stats, and math works because this game is about the story and the roleplaying. Check out their website for more info, and play it if you agreed with my above pros.
