Mount and Blade Warband
Mount&Blade Warband is an expansion to the original Mount&Blade game. Released by Paradox Interactive on March 30, 2010, Warband is the first stand-alone expansion for Mount&Blade. Although the game is very similar to the original, its primary upgrade features include a massive update for Multiplayer, the ability to Buy Land and Productive Enterprises and Prisoner updates.
A sequel called Mount&Blade 2 Bannerlord was also recently announced by its game developer late 2012.
A new faction called the Sarranid Sultanate was added to Warband.
