Diablo 4 has some very interesting features when it comes to cross-play, cross-progression, and co-op.
As revealed by Comic Book, Blizzard seems to have pulled off some kind of miracle with cross-play. Across five completely different platforms, you have cross-play automatically enabled.

Cross-progression is similarly an automatic setup. Both cross-play and cross-progression are built around Blizzard’s Battle.net system, so that may be the reason that Blizzard can promise such an incredible feature.
In any case, what this means is that you can start playing Diablo 4 with your PlayStation 5 at home, and then when you have to leave, you can carry a Windows handheld, such as the ROG Ally, the AYANEO 2, or the GPD Win 4, open up your Battle.net account on the Activision Blizzard client, and pick the game back up wherever you had to go.

The good side is that enemies scale to each individual player. That means low level and high level characters alike will get fair
