WotC license restriction?

Postby Yuioup » Tue May 18, 2010 4:11 am


First off I want to say: What a brilliant game! Well done! I played the demo and it looks really good. Actually I was toying with the idea of developing a game using simple graphics yet a complex AI/rule system. What you have created fits to close to 100% of what was in my head.

But I AM really curious about one thing: How did you get around the license restriction imposed by WoTC?

I'm talking about this one:

Q: Where's the experience point table?

The d20 license restricts some information from being included. Specifically…

"No Covered Product may contain rules or instructions of any kind that:

* Describe a process for Creating a Character
* Describe a process for Applying the Effects of Experience to a Character"

The restriction is mentioned here:


I'm just wondering because I thought it was impossible to make a game using the D20 system that includes character creation and leveling. Did you acquire a licence from WotC?

Never mind. I did a bit of digging. I found this post:


Basically there's a difference between the OGL license and the d20 license.

What I quoted was the d20 license and that is not what Knights of the Chalice uses.

This site also explains it (at the bottom)

Ok I understand it now.

Yes this is it. Another thing is that although they have a right to their descriptions (the text itself) of character creation and level advancement, they have no right over the rules themselves. Meaning that any game could roll up characters using 4 dice minus the lowest one without owing anything to WotC. As for the XP it follows a recurrence relation xp(level)=xp(level-1)+1000*(level-1) equivalent to xp(level)=level*(level-1)*500, of course they have no right over this particular sequence of numbers.
