Sasquatch grabbed the trademark when WoTC let it lapse, similar to TSR. The new game system and setting are different from the original. Otherwise, WoTC could have sued over IP misappropriation.
Sasquatch snatched the expired Trademark. They didn’t own the IP and couldn’t raise enough funds, so they bombed spectacularly.
The company is defunct now, so Hasbro could totally put the books back on drivethrurpg. They could easily contest the trademark using the “prior work” defense and their lawyers too. The pdfs were originally on rpgnow before WotC took them down during their 2008 hissy fit. Drivethru may still have the files on their servers if there wasn’t any hiccups.
Altho I wouldn’t be surprised if WotC actually lost the files and physical backups too. Considering that they put up the Amazing Engine and Star Frontiers pdfs back up, I suspect they did.
i did not know that. Huh. I wonder what other trademarks are out there to be appropriated...
