Diablo 2 Resurrected It's like a remaster Mass Effect for me. They don't make a new game, they repeat the old one, it's not same. Larian is making a new game, which is why action happend 100 years later. (correct me if I'm wrong)
Your question: how to love this game?
This is not old BG. And do not think that game should be similar, then it will be easier for you. It's still BG but absolutely new. There are 20 years between these games and this is not a remake or remaster, it's normal that they are so different and also made by different developers. What could affect the style.
also, do not judge game by early access, it is created for test. a lot of things can change, you shouldn't expect it, I'm just saying it's possible.
I also want to say that Larian is trying to attract new players, rather than focusing only on old fan base, and that's right. Do you know what that means? Some things will change for a new audience.
