Why do people Mod Game's?

[Jadsta]

I don't understand why people hack games like COD for the highest prestige either, but modding games for other reasons is fine. People do it because it allows them to often make the game a lot more fun and entertaining. Think about Counterstrike: Source for example. Without mods it would not be half the game it is today, since there's so much more you can do with modding. It's a community-made game in that sense.
