This modded map pack itself will sadly break your computer if you're running a lower end potato, as the creator explains:

The ludicrously gigantic map has room for up to 50 civs, but seems to break after around 30 (not to mention all the time spent waiting for 30 civs to take their turns after yours). Thankfully less than a week from launch, an intrepid modder has already taken care of that for us – but be warned it's a bit buggy at this stage. If you scroll through the list of available Civ VI maps, you'll notice one is missing: Earth! The closest thing available in the base map selection (before any DLC arrives anway) is the Continents map, but it's not actually the tried and true Earth map fans have come to expect. Looking for other Civilization VI guides? Check out: Below we cover the mods currently available to help fix those oversights and round your Civilization VI experience. While Civ VI features loads of changes and upgrades from the previous entries, there are still some issues that need to be worked out and a handful of elements from previous games that didn't make it into this one.
