NQMod

NQMod is a modification for Sid Meier's Civilization V that aims to balance the game and provide new play options, such as preventing the AI from building Wonders.

The developers provide two packages for installation; Single-player only, and Single-player and Multi-player. The latter is installed as if it were a DLC package, and is transparent to the game itself. Using the mod in this fashion allows the player to keep the functionality of triggering Steam Achievements.
