If you don’t know D2, it’s definitely interesting. It also depends on your attitude. D2 should not be considered an item grind game. D2 is fortunately a little more game with different priorities.
That starts with the classes. Unlike D3 where basically all classes feel identical because they are bent to fit the end-game competition, D2 always offers a playful and perceived partly strongly changed gameplay, depending on the skill within the class and depending on the class.
And then you are also less driven in the game to want to get through at all costs. Getting through is not the point of D2. Playing the world has a much better and greater impact here, and that’s how you should approach it.
It’s very liberating and at the same time D2 offers a better arc of tension, although it also has its hangs.
For example, the long way through the monastery and then through the prison and then in the catacombs to Andariel is a bit monotonous. From a story and suspense point of view, much more could have been taken out of the whole thing around the cathedral/monastery and it could have been more profound and underpinned with side branches that have more significance.
But overall, the acts feel very different and are entertaining.
In D3, everything was rather dry and monotonous. There were fewer situations here where I felt tension at times. For example, in the archives of the mage from Act 2 in the desert was quite nice. Even better for me was the way to Asmodan in act 3 as soon as you finally got past the wall. I would say that this area with the snow zone and then in the mountain and there in the tower, was for me the best section of D3. Here I had finally felt a little Diablo Feeling and the way had been fun. Asmodan was for me also the best of the whole bosses, apart from his whiny nature. But he had so the blow Diablo boss like from part 2.
But if you already know D2 inside and out like I do and can name practically every item from green and gold on without identifying it, $40 is just too much money. If it ever costs $15-20, I might consider it, but just maybe.
I would like more a D1 including Hellfire Add On as a remake. Because one should miss here the classes like Monk, Warrior and Bogi a few abilities and best still the barbarian and the bard integrate, which were already hidden as a template with in it^^ Of course with own skins and a few talents.
That would be quite a nice thing. Also the Add On Hellfire has been well done at that time. If I remember the crypt with Nakruul at the end, it had a good atmosphere. Nakruul was just a bit too unspectacular in his combat and too simple^^
