Hey Thomas,
Good to see someone from Australia 🙂
I recommend you try and work with the existing KQ4 remake, from the Magic Mirror games team. Some good people there.
It’s been proven in the Sierra community that people who ‘go it alone’ or try and also remake something when others are already doing it generally fail (and the better project usually fails, too, from lack of team members).
Also, definitely, don’t approach Vivendi about a potential remake.
Just some friendly advice. Wish the assets were public domain also though 😉
