Virtua Fighter is almost perfect for the E-sports scene, though it's not a series I have much personal experience with it's definitely one I can imagine finding a super dedicated group of people getting into it. And honestly, I think just for the smooth and fluid fighting that top level VF has, based on what I've seen, makes it a lot of fun to watch. Though maybe that's just me. Also releasing a Sega Saturn controller that's compatible with modern consoles sounds phenomenal. Nintendo already has gamecube style pro controllers for the switch, so Sega making something third party sounds simple enough.
Yeah the original Fantasy Zone games already have a mobile game feel to them, in the best possible way. It would be an easy fit into that model and would probably attract a fair few casual player and old school Sega fans alike. Plus Sega Heroes gives me at least a little confidence it's not going to totally scam players, even if they game does have some questionable monetization.
Sakura Wars is getting a revival (as an action game but I digress), Fire Emblem is at its absolute biggest it's ever been, Valkyria Chronicles has been doing well, and the Switch seems well fit for strategy games. We've not had a better time for a Shining Force game in years. If we can get that and Advance Wars back we'll have a full 90's/early 2000's strategy resurgence on our hands. Hell, if they wanted they could even work the dating sim mechanics in there alongside the strategy stuff. I know that's not ideal for some people, but as long as the strategy gameplay is good and the main focus and that's what it takes to keep sales up so we get more... I can't imagine it being too big a deal. Especially if they get the Sakura Wars people on it.
I have never considered the concept of a Ryu Ga Gotoku Studio developed Panzer Dragoon RPG before but now that I have... I think I'm drooling a little.
Real talk that is the best idea I've heard in regards to reviving PD. Hell between the success of games like the Witcher 3 and the hole left in the market by Bethesda's recent foibles this is kind of a great time to release a massive open world RPG. What's more, despite my limited experience with the series, Panzer Dragoon has such a cool and unique world as far as fantasy worlds go that it would easily cut out an identity to separate it from the crowd. Add that with dragon mounted shooting and you could have a completely unforgettable experience. Like imagine ridding across a vast landscape atop a dragon, notice a town being attacked, swoop down and getting into an aerial battle with some monsters. Land in the town and they tell you about a cave full of the monsters and you have to go there on foot and... well you get the picture. God damn I wish I'd thought of that.
I think that new Yakuza engine could also be fitted into a new Jet Set Radio if allowed. Admittedly similar games aren't exactly huge right now, but I think that might be to the series benefit, it can be a unique experience amidst the current gaming landscape.
