Excellent question! No.

If Sega decides to emulate Saturn games, do it on all platforms. Don't just do it for Switch.

Also, 3rd party games are always a possibility. I mean the Playstation store has had plenty of Capcom games.

No. SEGA is contempt remaking a few first-party games. 3rd parties are porting Saturn games to Switch. Mostly Shmups.

Its one of the harder systems to emulate. I would love it if they did as It's one of the few consoles I don't think I have ever played a game on it. I never owned it nor did any of my friends.

At this point, Saturn emulation has gotten quite good. I think virtually every Saturn game can be played at this point. People are even making English patches for notable Japan only games.

A few Saturn games have been ported, but none relying on emulation.

No. Genesis/Mega Drive is Sega's bread and butter from back in the day so I suppose it makes sense to have the games available. I don't see Saturn or Dreamcast happening because they're harder to emulate.

Yes. Sega Saturn and Dreamcast. But in the distant future. I hate NSO, but it seems to go wild with different hardware emulations. 

I get it that if Sega were to ever start re-releasing its Saturn and DC library, that it would probably make sense to have official releases of some of the games before it coming to a service like NSO. I mean, I am sure that they could sell a re-release of Panzar Dragoon Saga at $50.00 MSRP without any major rework and probably sell at least 10-20k units. I just wish that they would start this process because these games are starting to fade into history.

You know, retro games have a shelf life. Most people in 2021 are not going to find enjoyment playing a game like the original Phantasy Star which is currently being offered from Sega on NSO. Even gamers who might have played this title in the 80's would probably have trouble going back to it because RPG's in those days required such a large investment in time and effort compared to today in order to experience the payoff and reward. I know because I am one of the very few people who still play these types of games. You can get into them, but it takes more time that most people are willing to commit with our modern attention spans. Let's not even mention that instruction manuals in those days were basically essential to get through the game and that is not coming with your NSO subscription (I believe). That said, a game like Skies of Arcadia still would play really well for most gamers in 2021: it has a smooth difficulty curve, and it feels a lot more like a modern RPG than Phantasy Star (the only addition it might need are save states because I remember some of the dungeons requiring about an hour of gameplay between save points at times, but I think that should be default on NSO).

And I am not trying to be hard on Phantasy Star, it is an amazing series but it's just only going to appeal to a very niche audience who probably already owns the game on 10 different platforms. Instead, why not release Phantasy Star Online? It would be perfect for the NSO and why not bring back online play? This would be a huge hit, in my opinion.

I wish that we could move beyond the 8 & 16 bit era being the default game library for release on these online shops/platforms. This made sense in the Wii days on the virtual console back in 2008, but an equivalent retro title today, 13 years later would put us firmly in the N64/Dreamcast/Gamecube eras.

I don't know about the Dreamcast but there is a game that runs on a Saturn emulator for the Switch now, and modders managed to put any Saturn game to run on the Switch based on this emulator

Switch has some DC ports already. DC isn't hard to emulate at all.

Yeah, we're pretty much not going to see any major third party RPG or basically anything that is worthy of remaking or releasing seperately hit NSO, especially if it's past the 16-bit era. Look at what Square Enix just did with ActRaiser.

We got Chrono Trigger on the Wii VC at a time when publishers hadn't yet collectively figured out that they can make more profit with remaking or porting beloved classics and selling them on their own as opposed to dropping them on VC or subscription services. That just ain't happening now. The vast majority of the third party content you'll see on the NSO are titles that the publisher doesn't have faith or desire to remake, port or throw in a compilation as a SKU.

That being said, I would be perfectly fine if SE never attempts a modern remake of Chrono Trigger, and if and when the day comes when Sega gets its head out of its ass and realizes that people would pay good money for easy access to Panzer Dragoon Saga and Skies of Arcadia, I hope they hand the remaking/porting duties off to someone else that knows how to take care of it.
