I agree with the sentiment, but remember how everyone was clamoring for N64 emulation on Horizon, and it (from my experience, anyways) is still problematic? That's kind of where DC emulation is at right now with an alpha that, yes, while I poked fun at the glitches, I am genuinely excited for more of the arcade games that, if we're gonna be honest here, have about as much of a chance of MUGEN coming to the Switch via homebrew as they do through any official channels. SNK is only relevant in the most hardcore of the FGC scene, and the future of the Marvel Vs. Capcom series post-Infinite is looking dim in spite of rumors of MVC4 and how much Disney likes to meddle with things because they want to push the MCU so hard when there's many characters who haven't had a presence in the MCU in any form or fashion who should've been in Infinite *coughs in X-Men, Fantastic 4, Punisher, and many others I haven't listed that would be cool to see on the roster*. Melty Blood has been superseded by UNIB/UNIST/Anime in Pretentious Title (would love to see either or both on the Switch tbh, and yes, I know the title makes some sense in the context of the game's poorly proofread story mode). And that's not going into the other games that I doubt will ever see a Switch release anytime soon (Shenmue, the Sonic Adventure games, Crazy Taxi (actually wouldn't be surprised to see this one, but the second one...again, licensing...), Ikaruga came to the Switch, though it's not like it's not on every device under the sun).
If anything, after DC, I think Saturn emulation would be cool all things considered, though given the current state of even Yabause, it would be haphazard on the Switch. Not even the port on Lakka runs perfectly (and that's the case for the PS1 as well when it runs better in Horizon oddly enough). GC emulation would be nice too, but I think that by the time we get hardware that could run it portably at consistent speeds and be reliable and not be the GPD WIN2, I wouldn't be surprised if it's when gaming becomes more service based and companies actually try to do the whole streaming box idea. Maybe I'm being cynical, but with how dystopian everything is starting to become these days (Walmart cutting down costs by employing more robots to even my local stores, people starting to become more accepting of microchip implants in Europe and that one company here in America, and Samsung phones not being able to uninstall Facebook), it's hard to put a happy face on when you see stuff going on that makes you question whether you want to start a family and raise kids up in a world that's primed for something like China's social credit system.
Damn, how did I go from talking about emulation to politics?
