The Neverwinter MMO already exists, and is free (apart from the rather predatory monetisation system). graphics aren't as nice as this game, but it's far from the worst looking game still running. Want romance? Good news, people rp in the Moonstone Mask regularly, and if you ask politely you might even find people willing to erp with you.
I like MMOs, I do, but I also like single player games that can be played co-op. And just because a company can make a good solo game, doesn't translate to being able to handle an MMO. Several game companies recently tried out the "live-service" aka MMO style game recently and found it to be a real struggle, because they were not prepared for the demanding reality of a game that is continually progressing.
