It will get the post development Quest however not on release.
Then you're releasing a remastered 2006 game with practically no content at launch, which amusingly is exactly the complaint in this and the other topic only without the excuse of being a fully new world and game system. And you think that'd succeed?
And no it wont be a monthly Subscriprion because its a Free to Play game like PSO2 and NGS.
Considering your original point was that the 250k total subscription-paid Universe Network Mode accounts "would be broken on day one", making the hypothetical remaster free to play is comparing apples with oranges. A subscription fee content-withheld game vs a free version of the same game with no fewer features for the lack of entry cost? Gee I wonder what the biggest reason for the latter getting more accounts might be...
I won't lie, I wouldn't mind a remastered version of PSU's single player mode, if nothing else. The online mode was...eeeeeh
Thanks for exemplifying my point there.
