Entgegen landläufigem Vorurteil, war Cthulhu D20 ein Riesenerfolg. Erinnert euch, das Spiel welches in Deutschland etwa zur selben den meisten Lärm machte, war Degenesis.
Etwas über tausend verkaufte Bücher. Perspektive ist alles.
Aber lassen wir MonteCook selber sprechen:
Re: Why did CoC d20 fail? The easy answer to the question posed in the subject line is this:
It didn’t. It was a monumental success. CoC d20 had two goals:
1. Show that d20 rules could be used for something other than D&D fantasy.
2. Sell lots of copies.
It accomplished the first by its mere existence, and by making a dramatic splash in the industry (which it did, beyond WotC’s expectations). It accomplished the second by selling out of its initial print run (around 35,000 copies, I think) quickly.
These things were not CoC d20’s goals:
1. Create a long-term product line (or any product line). It was always intended to be a one-book thing. The idea was that D&D fans would buy it, try it, and some small number of them might then try regular CoC.
2. Please existing CoC fans. The target audience was D&D fans, not CoC fans (the latter already had a CoC they liked).
3. Make CoC as popular as D&D. For a lot of reasons, this is just impossible.
