Just a quick tip ...

Dear people who made this ad on Drivethru RPG:

You might want to consider all the non male GMs that are work hard to give their players a great and fun experience in their gaming lives. They work just as hard, frequently having to deal with a lot more crap that male GMs don't have to put up with. They too deserve an ad that doesn't exclude them.

Really, it's not that hard to do either.

Here are some example copies:

No GM, No Dice ... Bribe them with something Nice
No GM, No Dice ... Give gifts to keep rolling.
Think of your GM ... Think of your Character ... Get your GM a gift that keeps your character breathing.

Now, are they all good copy? Not really. But when your ad excludes half of the population you can clearly make the argument that it's bad copy too.
