I was never particularly happy with it sadly, most matches on Switch were laggy which especially irritated as game music+sound are tied to frame rate, making it all rather unpleasant.
Funny thing is I was shocked to see Ultra Street Fighter 2 on Switch is still reasonably active, at least more than you'd expect. I still fire it up every once in a while on training mode w/fight request on. Just be prepared for some flowcharty Kens + violent Kens...
Also, unrelated but why in god's name are there not PPP and KKK inputs D:
I wish the game allowed you to queue for matches across multiple games/modes simultaneously as well as supporting cross platform multiplayer. As it is the player base is split across four platforms and those are split further across four games then further still between Ranked, Casual and lobbies. It's a shame.
Yeah this is the big problem aside from latency, the online's segregated into way too many different mods, diluting what small playerbase is already there
From recent play, 3S seems to be the most active on Switch, though even then it'll vary.
This collection sold a million copies and the online's dead everywhere. A perfect example why crossplatform online play needs to be the standard.
