Pseudolonewolf has abandoned Mardek to work on Taming Dreams. If I got his permission (which is near impossible, since he is not currently on any forms of social media), I could finish up the series.
Guys, Pseudolonewolf said on FigVerse Wiki that he plans to start Mardek 4 after Alora Fane: Creation is finished. However, the game probably won't be released for a while, as Alora Fane is not near being completed, and big games like Mardek take a long time to code. If he is to release Mardek 4, it will probably be in >4 years.
McLeod's music are fully free, you just have to explicitally credit his work; more details are on his site, incompetech.com, there you'll find all the answers but, as we said, it's free, so... go look for some good music, friend! :)
I doubt Tobias will ever finish this game, due to his depression and brain tumor. It is hard to contact him as well, so there is no way to get someone else to finish it.
@AlinG49, I would but I need the permission of Tobias Cornwall (AKA Pseudolonewolf) to make it, otherwise it would be already copyrighted and I could be sued.
