Inspired by the ancient tales of the Arabian Nights, Nadirim is a free to play browser-based MMORPG developed and published by independent studio Twisted Tribe. The game requires no downloads or subscription fees and is compatible with most popular internet browsers. Even though it's a browser MMORPG, the game features 1 expansive game world, no loading screens or instances.

Nadirim includes 3 playable classes, Rogue, Sage and Warrior. Warriors are the typical melee class of the game, wielding Arabian style weapons such as Shamshir's, they're skilled at both offensive and defensive abilities but lack in range attacks. Rogues are the thieves of Nadirim, utilizing hand to hand weapons such as the devastating daggers, Suwaiya. Players using a Rogue can expect stealth attacks and sneaky abilities. The final class, the Sage, are the magical wielders of the realm, using spells to both heal their allies and damage their enemies. Sage's can also use crowd control abilities and AoE spells.

The game does use an Energy system that players of browser-based MMORTS games will be familiar with. Certain actions, such as traveling or completing quests, requires a certain amount of energy, once that energy is gone, players can no longer perform any actions. Players can refill their energy by logging off for a number of hours or purchasing a boost from the item mall. Certain actions, such as PvP combat and trade, required no action, giving players activities to do if they've run out of energy.

Nadirim uses a unique method of travel, caravansaries. Caravansaries can be found throughout major towns and cities and once visited, it unlocks the caravan to use as a travel point. You have to unlock each one on foot but once you've done so, you can freely travel between them making quests and other exploration tasks far easier.
