While we haven't seen Sakura Wars in the west except one game, they have announced a mobile game of sakura wars....and its horrible.
What has Sakura Wars got to do with anything? They have loads of great mobile games available.
We're not here to talk about Nintendo's future here because while they have their own problems, it isn't anywhere as problematic as how SEGA is facing here because they can last very long.
If you want to discuss SEGA, then at least listen to what others have said... As others have said SEGA are not at risk of going bankrupt, they're profitable, even with the very few games they released in 2015 because most have been pushed back into 2016, and a 90% drop in profits they're STILL profitable. And if they weren't, SEGA Sammy have load of money and a hell of a lot of assets to sell off before they go bankrupt... So you can put that dream to bed.
Right now there are a few things that pop into mind?
1. How can SEGA win back its audience? Abandoning strong IP's like Shinobi, Phantasy Star etc isn't a smart move because the audience for those games are still strong in demand. Western Studios that SEGA owns are not going to be owned by SEGA if they keep making losses.
None of those IP's are abandoned, there was a new Shinobi on the 3DS a couple of years back and Phantasy Star is in active right now... SEGA have revived series after a decade before, I don't think SEGA have ever said a series is abandoned...
Secondly all of SEGA's western developers are incredibly profitable, so why on earth would they sell them off? They wouldn't, all of their series are critically acclaimed, million sellers which sit in the charts for weeks on end.
2.How can SEGA make profit if nearly every game they make is niche to begin with? There's some argument that their franchises aren't niche but seeing as how they keep many of their IP's sell less than more, they are still niche market.
Just because a series is niche in one region doesn't mean it's niche world wide...
Sonic isn't niche
Phantasy Star Online isn't niche
Yakuza isn't niche
Company of Heroes isn't niche
Total War isn't niche
Football Manager isn't niche
Dawn of War isn't niche
Chain Chronicles isn't niche
Persona isn't niche
etc etc
Also I don't think you know what niche means, it doesn't mean not profitable, it means small audience... Which isn't a problem, plenty of companies survive on only niche titles and are still profitable. SEGA have both niche and popular titles... And they still regularly turn a profit.
SEGA are in no trouble financially... And the REASON they've lowered their profit forecast this year is because they've delayed most of their games into 2016 to promote quality while Nintendo this season have released a looooaaad of trash.
