Bringing up PokeMMO is interesting, because there's also a fair amount of content and potential for more: a full battle frontier, pokemon contests, secret bases/decorating, recent mainlines also come with DLC campaigns probably not incomparable to an expansion pack as well as raids. Some sort of official competitive format would work wonders as well, given that mostly we have VGC in mainline, which is only doubles, and smogon as a general unofficial meta.
An economy could be managed through not-monster means, like TMs and bottle caps, but that would make it awfully grindy too
