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.
Really? When they have been releasing 2-3 games a year? I can't imagine franchises that get one game released a year are going through.
