Hello everyone, I wanted to ask what exactly means to play online diablo 2 resurrected. I mean, if I am online, can I do the story with a friend of mine and finish the game together? Because we absolutely adored to do the storyline of diablo 3 together and instead we found super boring to play the rifts or explore the game again once finished, that was not really too much fun after a shortwhile, no matter the new seasons etc. What is absolutely stellar is to be able to enjoy a new game together with your best friend to play games. Is this an option in diablo 2 ? Or otherwise what can someone DO when playing online with a friend on D2R ? Cause I checked online and couldn’t find this answer anywhere at all, they all mention it can’t be cross platform and bla bla bla but nobody explains exactly how is the multiplayer 
Thanks for any help!
PS: I had to post this again here because since i don’t own the game it won’t let me post it in another section of the forum, lol!
