Some game companies understand that modding extends the life of a game, and embrace the idea. Others are somewhat less enlightened.

Take-Two Interactive, makers of the Grand Theft Auto series, recently sent a threat letter to the developers of a popular GTA4 modding tool called OpenIV. Lacking the resources to fight the threat, the OpenIV folks stopped distribution of the tool. Fans of the tool -- and the game -- are furious.

Dear idiots at Take-Two: this was a stupid move. You're going to lose far more business and consumer goodwill than you could ever hope to (somehow?) save by shutting down this tool. Here's a suggestion: stop letting your lawyers guide your business decisions.
