Facebook ads are to this coming decade what 3am TV ads used to be 20 years ago; low budget and often humorous.
I keep seeing ads on Facebook that make me chuckle or scratch my head, like this one.
How is this different than regular paper?
The Facebook ad system allows you to pick your target audience, but keeps you to a tweet-like level of text that often cannot get across what the advertiser is trying to express.
By the way, Gaming Paper appears to be just rolls of paper pre-printed with square or hex patterns. Basically, wrapping paper with specific patterns. If that was the help you needed in drawing your roleplaying or miniatures game, consider yourself informed.
