I have plaid all three parts, and I love all of them. But I would like to say that the second part was the most challenging for me. Some levels are really hard, and I had to go through them over and over again before I could finally complete them. The most frustrating part of Diablo II is that I found only one rune. I tried to create other characters to go through the same missions, and again I kept finding the same rune. Recently, my friend told me that it is possible to purchase runes from https://www.yesgamers.com/diablo-2/runes So, I would like to try playing with more than one runes.
