Damn, every JRPG franchise I want to get in on is dying. Must be my bad luck. Okay, I am NOT going to start FF with FFXV....really, universe...I'm not.
What other franchises are "dying"?
Anyways, Star Ocean probably wont completely die but it might get temporarily frozen again like what happened with the last one. If anything - it'll sell somewhat decently and not be a complete flop.
If we're lucky we'll get a follow up remake/enhanced port like we did for SO1/SO2 for SO3.
Anyways, as for FF games to start - would not recommend to start with the most recent. There's plenty of other games in the series.
If you are a Playstation only gamer - its highly recommended to go for FF7 on PSN.
