My first thought was "isn't D20 a trademark of WotC?"
My 2nd thought was "is there a 50,000 British Pound market for a 3x adventure path distributed via tablets?"
My 3rd thought, after playing the video was "aren't these the same guys with the cardboard gaming tables?"
Actually, my wife had the same thought when she heard the voices - the Spanish accents are so strong we thought they were Italian, subtitles would have been helpful.
Then I read this:
and I knew the journey was going to be a good one.
So, Digital D20, or DD20, or D20 tabletop Role Playing Game Campaigns is a method of distributing D20 RPG adventures from DigitalD20 Ltd to your tablet, and perhaps those of your players.
Yes, you can't use the underlying software Gamethrough without using adventures purchased from DigitalD20. No writing your own adventure or going off the adventure path here it seems.
They do offer a sample page from the first adventure:
That is going to be painful to read on an 8" tablet, and not just because of the size of the font and the background graphics - the English is awkward at points too.
So, they give is a short write up of the campaign:
They've set a fairly high goal for a project that is aiming for $80,470 using today's conversion rate. For a rule system that was supplanted by Pathfinder and a project that they can't be bothered to present in proper English.
First impressions mean a lot and Digital D20 isn't leaving a good one.
