Project Xcloud: MMO from mainframe should not appear exclusively for Xbox

On a cloud MMO with the preliminary name Pax DEI, the Finnish developer mainframe for Microsoft should work. Since the game is developed for Microsoft, you have previously been that it would appear exclusively for console and / or PC. But that does not seem to be the case. New information from Jeff Grubs is to become Pax DEI a multiplatform game. Apparently, Mainframe has received 23 million for development. But the financing does not come from Microsoft, which is why there is no exclusivity. Furthermore, there is a speech that a party should have played the other to increase the amount of money you could get. The exact background is not clear.
