If you want the press to pay attention when you contact them, answer one question for them very quickly: Why do I care?

Do a lot of people play this? Give me specific numbers.
Is it growing? Because that would help a lot; again, specific numbers.
What need does this serve that regular video games don't? Be specific. Who plays this game, where are they and why aren't they served by better known products?

Give specific, thorough and interesting answers to these questions before you're even asked, and you will get much more response.

Editors, writers and bloggers are swamped with requests from people who want to be written about. They are looking for a reason to hit delete and move on to the next one, so don't make them figure out why this is newsworthy, tell them.
