So what is the feasibility of creating a retroclone of Warhammer?
It's a fact, the rules of a game fall outside of copyright law. However, the presentation of those rules are covered.
Does anyone have the mettle to sort the presentation from the mechanics, so that the legal minefield can be successfully negotiated and we don't end up with a huge pile of cease and desist notices in our in-boxes?
Let's take the statline, we all recognise this:
M | WS | BS | S | T | W | I | Ld | Wp | Int | Cl
how core is that for a game to feel like 'hammer? What if we just swap it out? Maybe with...
D | CS | RS | F | R | HP | Q | Cm | Md | Sy | Kl
Distance, Combat Skill, Ranged Skill, Force, Resistance, Hit Points. Quickness, Command, Mentality, Stoopidity, Kewl. Does it feel right? Is even having them in the same order legal? Alternative suggestions welcome!
What about the To Hit Chart? I'm pretty sure that the table can't just be reproduced legally. can the same outcomes be resolved in a different presentation, could it (should it?) perhaps, be written as a formula?
And what is the desirability? While it could be a great reference-point for scenario development and players, would you want a Old-School Warhammer clone?
