Exclusive for the Switch.
Since the first Bayonetta is on Steam, I was hoping that game would make its way to GOG. I mean... I have both Darksiders, but...

Well... SEGA is one of the largest publishers not yet on GOG.

thats awesome but i've already gotten that news and i'll be getting it when it releases
and the first bayonetta wont be coming to GOG anytime soon

Well Darksiders is a begrudgingly good alternative. Hell I think of them as Bayonetta without a sense of humor.

Darksiders is more Zelda-like. The best (only?) alternative to Bayonetta on PC is Devil May Cry series, but that's in Capcom hands (at least we got some games from them here).

Well, Bayonetta 2 is a Nintendo published game in which the Big N funded the development so that is never going to make it to PC, and it seems to be the case with Bayonetta 3 also.

I am not sure if Nintendo also has the exclusive publishing rights to the first game, but it is quite possible as the Bayonetta HD remake was included with Bayonetta 2 on the Wii U, and Bayonetta and Bayonetta 2 also are coming to the Switch.

First Bayonetta is available on Steam though.

Yes, but that was when Bayonetta was a multiplatform game and the publisher of the property at the time made the deal. If Nintendo owns the publishing rights to the Bayonetta series now, then the original won't be making it here.

Ownership rights change, publishing rights change, too, which is why games get pulled off of GoG every year and previous exclusive games on one platform go to another. Look at Microsoft buying Rare from Nintendo and MS buying Bungie studios and taking Halo as a Mac exclusive and turning it into an Xbox and eventually Windows PC exclusive.

Actually, I think Bayonetta 2 was announced this year for Xbox One and PS4 despite Nintendo being the financier of the game.

I really didn't think Nintendo would agree to a third Bayonetta (the second one didn't exactly sell well), but hey it's something to play on the Switch. Source? So far the only thing that's been announced was a Switch port of Bayonetta 2 along with the first game.

Not really news that its with Nintendo; but I'm still puzzled a bit by that. I played the first few stages of the 1st one and it kind of opposes vehemently the family friendly face I remember Nintendo wants to keep with its oversexualized, ultraviolent and antireligious style.

So... what exactly makes this Bayonetta series so special that the masses should care whether or not it appears outside of the Nintendo console?

I recall watching some youtube videos, and thinking it is a generic beat'em up game. What sets it apart from the rest of the genre, the nerdy looking female protagonist with glasses?

Nerdy female protagonist with glasses.
But also witch time(bullet time but based on actual reflexes).
And hair kung fu.
And hair torture devices.
And collecting records for a bouncer demon guy.
And really bad Italian.
And hair kung fu.
And a very subtle hint of sexiness.
And hair kung fu.
Basically hair is all she wears. Hair and high heels. And guns.
Imagine a game with a female version of Dante and the developers found the spot where combos come to a stop and yanked it out.

Nintendo tend to develop family friendly games probably because it's marketable towards a bigger audience, and getting kids on board is usually a good way to secure long-time fans. Also a game can be family friendly, but still difficult (just look at many older games), also Nintendo have published low rated games with some pretty disturbing subtext. like Giygas from Earthbound, 02 from Kirby (this series has quite a few disturbing elements dotted here and there, usually final bosses), World of Nothing and River Twygz Bed from the E/3+ rated Super Paper Mario, and they even published and helped in the development of the great psychological horror game Eternal Darkness: Sanity's Requiem.

Nintendo may not be as gung ho about publishing M-rated games, but they definitely have their moments, especially since the beginning of the 90s ended and the ESRB was instated making it easier to highlight whether games are suitable for children or not.

When Nintendo got in contact with Sega and Platinum about publishing Bayo 2, they were probably very aware of what they were getting into (the original already existed as reference), heck, they even suggested Platinum should remove layers from some of the Nintendo character cosplay costumes added to the Wii U version of Bayo 1 if it would suit Bayonetta's character more.

Wait, what? Dante was a man?!? Could have fooled me.
