Yeah but for a game in 3 parts I can see it. Part 1 being what he actually recorded, part 2 being done by Tony with Glenn Hughes on vocals, and then part 3 being written by Bonnie with Andrew Freman on vocals since he can kinda match Ronnie vocally to some extent. Oh and obviously you keep Ronnie’s narration from the spoken word track for trailers and such.
He apparently kept a lot of notes as to where he wanted to go with the story in his planned two follow ups, and it’s not like it would be the only time he has had work completed posthumously. His autobiography was done that way actually. Where he wrote a lot of it but a few others filled in details for sections he started but never finished.
