I'll die on the hill that DS2 was misunderstood, and rather than being a poor game it just caters to a specific taste in Souls games, which turned out to be the minority.

It's rather unforgiving with Stamina and requires more in terms of positioning and timing to handle multiple enemies, such as lining them up to hit multiple in one swing or singling out a target to stunlock thanks to weaker poise. Healing also requires more consideration to pick the right window. I like that. It feels more like a harsh and dangerous world where you have to watch out for your own survival.

The Small White Soapstone often works for a quick trip to another world, earning souls, lifegems and regaining humanity with less commitment than a full summon, which encourages jolly cooperation by lowering the stakes and raising the reward. I like that.

I also like the changes to the weapon upgrades and the magic system. Pyromancy becomes an actual magic discipline, that can still be worked in alongside miracles, sorceries and particularly hexes, like having more attunement gives you more casts, consumables can restore spell uses and you can use materials to lower spell requirements, all of which affects character builds. Being able to respec means you can change or fix your build later on.

I'll concede that the learning curve is bad. There's more mechanical complexity to learn and less explanation than in DS1, and particularly the differences between the games aren't obvious if you go at it with the expectations set by the original.

In a way, that makes it a bad "Dark Souls" 2, since you're obviously expecting more of the same because it has the same name. Trying new stuff may be good, but changing existing systems is always a gamble whether the people trying and liking it outweigh those that didn't like it or never even tried.

That many people ended up not liking them was unfortunate. Particularly with DS3 going so hard in the other direction, the approval of DS2 has diminished even further. Its playstyle just isn't to everyone's taste, and many people conflate "I didn't like it" with "It's shit", which is a shame.

In summary, I think it's a good game, even a good Dark Souls that innovates on the original, but it's probably a bad entry point for the genre due to the steep learning curve, and a rough transition from more faster paced titles. I acknowledge it's not for everyone, but I liked it.
