I see right now that this would be in a clear violation with any licenses
not my own, which means both DIKU and CircleMUD. So screw d20 to hell and
back in a hand basket with a pink bonnet on it.

Ok, now I come to the question; are there any good systems out there that I
can use without violating laws to the left and right?  I am not overly fond
of the D&D 2nd edition system.  I tried searching on the web, but there are
little or no information about copyrights and licenses on the pages that
relate free game mechanics systems.

Especially for magic use, does any company have the copyright for the spell
circle/spell book/reagent system used in various games such as Ultima and
others? Or can I safely use a similar system as long as I write my own code
and mechanics?

Then for combat I would like something else, other than the THAC0/AC system.

I have seen several muds out there with a similar system, Materia Magica
and The Inqusition being two of them, if they have special licenses I am
not aware of, but I would like to know more about this before I start
working on the system (which will be very soon).

If anybody has anything to recommend, please, send me some links and ideas
to me privately, please.

Kind regards,
Torgny
