>>46657914Given you talked about RR, I'm asuming you mean the Ultra Games
Alola Postgame is carried by various sidequests and events (things like the Pyukumuku beach event, Eevee trainer event, etc), Battle Tree, Battle Agency (for as gimmicky as it is, its pretty fun), and Ultra Wormhol.
I'd say the Ultra Games have some of the better postgame content in the series, though I'll wholly admit that's because most of the series has shit postgame content if we're including every base game into the equation
