Activision Blizzard is not a good company. They have an abysmal track record for how they treat their employees, history of misogyny and abuse. Since the departure of Blizzard's founding members, the quality of many of their games took a noise dive.
They got one thing very right though, and that's account-level, platform independent save system in Diablo 4.
Being able to seamlessly switch between my PC, PS5 and Steam Deck is probably the coolest thing I experienced in gaming in a very long time. While it would be awesome not to have to buy the titles individually on each platform, it's a huge step in the right direction.
I can only wish more games supported cross-platform saves, because now that I'm used to it, I can really feel the absence of this feature in other titles.
(It would also help a lot with games preservation, if you could easily use old save files on newer platforms and remasters - as long as it's not all server-bound)
Hear hear. The steam deck is making me appreciate that the most. I initially hoped cross-platform saves would work for games on the Switch and PC, but I don't think I've seen a single game where that works. It's part of the reason the Deck has replaced the Switch for me. Steam cloud saving is usually flawless between Deck/PC.
The downside of true cross-platform is that it requires server side saving. Which usually means another launcher and multiplayer/GAAS BS. Diablo is no exception.
