Knowing full well the benefits of a healthy community, Valve has been one of the most supportive developers when it comes to modding.
This led to Valve, themselves, making sequels for this series, which as of 2011, has resulted in over 25 million copies sold (you can only imagine the total a few years since). Since it was a mod of Half-Life, gamers had to purchase Valve’s title to play the incredibly popular first-person shooter. One of the best examples where modding helped increase sales of the original work is Counter-Strike. They know that modding can serve to attract a larger audience to their game, which in turn will boost their image, and even bring in more sales.
In fact, many developers openly promote modding for their game, rather than seeing it as a violation of their work. Just like excellent reviews and high sales numbers, a good modding community is something every game creator dreams of having.
