Unfortunately, since then, Taleworlds Entertainment, the makers of the series, had somewhat neglected the series in favor of working on and releasing a standalone expansion of the original game, Mount & Blade: With Fire & Sword in 2011, which was set in 17th century eastern Europe and introduced primitive fire arms into the mix.
It was big jump from the original Mount & Blade that released in 2008. It’s been more than 4 years since Mount & Blade Warband released (or nearly 4 months if you play on Mac/Linux) and introduced the Sarranid Sultanate, the ability to create your own kingdom from your land holdings, marriage, multiplayer and much, much more.
