Hmmm... I can see how that particular niche of the gaming industry could be a challenge to monetize. However, if you become known as the go to person for their tools, you might build a solid reputation that you might be able to utilize by recommending affiliate products such as games or hardware. The main thing is to make sure it is a win-win situation. At the very least, you should try to build a list of those who are interested in gaming.
I hope this helps,
