You get to be a gangster, make a mob, earn(steal) money, buy weapons, and fight other gangs. You can also make alliances and possies to defend your gang, and earn more money.

Just read the directions

There's Graal classic (http://www.graalonline.com/?topic=classic) and Graal Online (http://www.graalonline.com/) 2 awesome free zelda like and massively multiplayer.

Also, for french speakers Nainwak (http://nainwak.krot2bic.net/) a really fun dwarf game. Its graphics look like graal but it's much funnier. A total delirium :D I never laughed that much for a game.

There's another MMP game out there called Rebel Dawn. :goodjob:
