...and abandoned the IP after the transfer failed. No, they didn't care for DnD, they only wanted to help Hasbro out of unconditional love. Makes sense
It wasn't a full IP sell it was essentially negotiating some licensing agreement with Tencent
https://www.enworld.org/threads/no-hasbro-is-not-selling-d-d.702378/We don't exactly know why Larian was mentioned in the rumors that they were involved with the negotiations but regardless it doesn't appear like the rights sale was ever on the table.
I also question why Larian would abandon the IP altogether if they actually did plan on selling to Tencent. Which is a company I doubt would be better to work for than Hasbro.
