I guess I'll bring up the elephant in the room and bring up and mention in reference to the
huge incident with THQ Nordic (and I deeply apologize if it's not appropriate to do so here), who not only was working with MS on their PC retail games, but evidently are working with MS on potential Switch games. To clarify, save actual talk about THQ Nordic's situation for the other thread, this is only in reference to their relationship with MS since it's relevant.
My question is who should MS work with instead? My vote: Majesco. They're not just still alive, but are making a new cross-media intended IP for Switch and PC
called Coba, and were just bought by Liquid Media Group last year. They seem well on their way nowadays.
Majesco as some may remember did indeed publish Age of Empires: The Ages of Kings and MechAssault: Phantom War on DS. As long as they can actually put out retail games, I see no reason for MS to go anywhere else now. Assuming they won't just do it all themselves now.
