And the first thing they (and yes, probably I would do if it were me) is charge a monthly fee to play. They certainly don't make money on ARX, do they? I haven't purchased ARX in over a year. Any corporation purchasing ED is going to want a return on investment. Yes, they'll lose a bunch of current customers that only want to play for free, but they may gain more as the monthly fee would (in theory, anyway) (1) pay for more robust servers resolving instancing issues and (2) pay for programmers to resolve bugs, fix issues, and provide more content.
Not that I'd LIKE a monthly fee, but if anyone expects that things would get better if ED were sold to something like M$, this would be something one could (and should) expect.
I disagree, required subscriptions are old school. If someone bought up ED they would monetize the heck out of it. Do something wacky and fun, like: you get 2 ship slots, and if you want to own more ships you have to buy additional slots with ARX. Add some ARX-store-only ships that have better capabilities than the credit-purchased ships that peasants fly in. Guns, components, all of it: better versions on the ARX store.
Loot boxes.
And THEN they would add an "optional" subscription that relieves some of the pressure that their new and improved ARX store has put on the game. For just 15.99 a month get unlimited ship slots, a monthly grant of 500 ARX, and best of all: the maintenance ARX cost of owning a fleet carrier is switched back to the old credits system (ARX maintenance, you ask? well that's a change that comes in the same patch that introduces the optional subscription).
Probably add in some log-in rewards. Log in for 30 consecutive days and get a green loot box!
They'd also fix a ton of bugs, like having to log out in order to browse the store. Fixed right away! Now when you log in, or jump to a new system, the ARX store helpfully opens op for you center-screen!
And these are just off-the-top-of-my-head some optimistic predictions about what a new owner that just shelled out millions of dollars would do in order to start seeing an immediate revenue stream from ED. Money does indeed solve problems, but only the problems that money cares about.
