Learn the basics before making such stupid statements. No offense though.http://mods.moddb.com/getting-started/learn-about-mods/ said:What is a mod?
Mod, short for modification is a term generally applied to a customised (or altered) computer game made by the general public. A mod can range from a total conversion with new gameplay, look and feel through to minor alterations which could include new models, weapons, maps etc. There are plenty of types and tons of styles, a mod can be anything the creators want it to be.
The purpose of a mod is to change the game and add an extra dimension of replay ability and excitement. Mods have even being known to outshine the original game, and playing such a mod may become even more common than playing the unmodded original. They increase the lifecycle and sales of games, benefiting both the players and the publishers who both get more bang for their buck!
