A little background on Archipelago. It’s built for the randomizer community (mostly A Link to the Past Randomizer) but with the multiworld capabilities they realized they could do cross-game multiworlds. There are over 20 games currently supported by Archipelago. You can have one person play Super Mario 64, one person playing Starcraft 2, another playing zelda, and another playing Factorio. Hell, you can just play them all yourself, a cross-game solo experience.
I believe the developer already has plans to put HotS and LotV in coming months.
Check it out over at https://archipelago.gg/. It does take a bit of setup but the guides are pretty straightforward.
