I have played tsunami for a number of years and find it to be one of the most involved and amazing muds I've ever run across. The world is HUGE, the classes, races, and subclasses are vast. There is something for everyone, quests, wars, invasions, pks, etc.

The pk system is unique in my opinion. It was changed quite awhile ago from losing/gaining exp, to coincide with our 'jihad' system (there are 5 religious orders you can choose to follow, each is friendly/hateful towards others).

There are also in game wars as well as shutdown wars to help people sharpen their skills, and gain a bit of free exp/gold. There is even an arena where you can fight other players to test your skills. Players can own and upgrade houses, as well as own different types of shops, from bars, to items, to heals. Tsunami is vast and complex.

It takes awhile to learn, but once you do you'll stick around. The community is closely knit and everyone knows everyone else. It's kind of like cheers :) Drop on by and give it a whirl. If you find yourself lost, needing assistance, or just want to shoot the breeze I'm usually around as Epic or Abaddon :)
