Luned: I haven't gone over to see the train wreck at the other forum, but it all starts to sound like...
a) The whole Jonathan Boakes thing with the Dark Falls from a couple years back, although somewhere along the line that got resolved in a civilized manner and the games returned to GOG.
b) The Candy Crush folks threatening to sue the devs of The Banner Saga for using "Saga", until they got laughed off the internet....
c) And just wondering, so how come this Cleve person didn't sue these devs? [url=]http://detectivegrimoire.com/[/url]
Cleve's kind of crazy is the kind of crazy that takes in facts, chews them up, and then drops acid before coming up with a solution to whatever problem he imagined existed. So, to answer two of your points:
b) it's kind of like this, in that Candy Crush threw out a C&D notice as a standard action for protecting their intellectual property. It's actually a requirement for business to actively protect their trade marks and dress, lest it fall into common use and no longer be protectable under law.
c) That's not actually related, since Detective Grimoire is easily distinguishable form just plain old Grimoire. Even as pants-on-head crazy as Cleve gets, he probably wouldn't try to go after something like that because it's apparent that the two are different. This hullabaloo was probably (who knows with a man who claims to have a doctor's note authenticating his status as a living fossil, the last living neanderthal) because the names for the two products were identical: Grimoire. Full stop.
You're not missing a lot by not listening in. It's just internet drama. But like reality TV, it's internet drama with the crazy dialed up to 11.
