Well, you could as well say the same about Shadowrun then, the two always came in a package
FASA just plain went down financially. FanPro meanwhile was a pretty solid German company, who at the same time also published Das Schwarze Auge, which is Germany's top pen and paper RGP. Germany's "standard fantasy" RPG like D&D, but
way more dominant than D&D is on its home market, and yes, I know that already is a lot. Basically you can't do pen and paper RPG here and avoid DSA
(conversely, D&D has basically made zero inroads here). Holding the rights to DSA, Battletech and Shadowrun was hence pretty solid.
But then they had some really weird business ideas: Selling off all the licenses for those franchises
except the novel licenses, on which they wanted to focus. So they sold off the DSA licenses to a new company extra founded for that purpose, and sold off the Battletech and Shadowrun to Catalyst Games. That... didn't work out and FanPro went down in 2012.
