I was a freelance writer for Hogshead*. The game line was actually quite profitable for the company: The money from it allowed James to put out less "commercial" but critically well-received pieces like Baron Munchausen and Nobilis. The truth is, after several years of running the place almost all by himself, he was burnt-out and wanted to sell the company. GW wouldn't allow a transfer of the license to another company, so he returned it to them (from what I heard, *they* were surprised) and sold the firm to the new owners. And, to be fair to GW, in all the years we dealt with them, they were generally reasonable and easy to get along with. The only complaint that I know of was that they could be rather slow on approvals, which can happen when a tiny company deals with a relatively huge one.
*(Sounds like a title from an old film noir movie. )
As for the game's future, the most likely speculation has GW eventually re-releasing it through their "Black Library," but I don't know anything definite about it..
Anyway, I'll be interested to see how a Hero version of it looks.
