I don’t see it working that way. I see missions being available in free flight. No credits, no progression, no purchases, no company, nothing. We just jump into free flight, click an icon, do a mission and that’s it.
I have no time and no intereste in having to spend hours doing stuff I don’t like to be able to eventually do something I like.
I’m not after the virtual money, I don’t care about points, I don’t need to buy aircraft. None of those mechanics are interesting to me. So I don’t want an unlimited credits career mode. I want those missions to be available to me without even using the career mode interface.
