Final Fantasy is life time but the other 2 will be on Gamepass by the end of the year.
there are basically no lifetime deals. what is more realistic is that Square sees no potential market that is big enough on Xbox for Final Fantasy VII... which is a self fulfilling prophecy.
japanese devs often not release their games on Xbox, but then they sporadically and without much of a pattern will release some odd installment of their franchises on Xbox, which will then not sell that well and they pause releases again for some time.
and then after doing that shit they turn around and wonder why their games have no fanbases on that system.
you can't just release Final Fantasy XIII out of nowhere on Xbox when previously you didn't release XII or X... but then release XI the MMO, but not XIV, the second MMO...
nothing about this makes any sense...
other publishers aren't better. Silent Hill 2: Xbox + PS2, Silent Hill 3: PS2, Silent Hill 4: Xbox + PS2... like wtf are you doing?
I bet if all japanese publishers, all the big ones at least, would consistently release every single of their games on both systems the sales on Xbox would slowly grow larger and they would basically grow a new audience, but no, can't do that... let's make a weird exclusivity deal, and then after it's over still not release it on Xbox.
but something tells me FFXVII will be multiplat again for some weird reason, and will again sell not well on Xbox, because XVI wasn't there and the VII remake was also absent.
