Dark Souls seems like a fine game, though not really for me. Dark Souls fans are irritating cunts that have permanently put me off the idea of giving the game another try ever.
It's not for everyone.
I've never had a problem with the fandom, but "git gud" has been stale for years.
What's funny to me is that they have this reputation of playing the hardest game available to gamers today, yet I've got a funny feeling that if they played some of the harder games of the previous generations like Jedi Outcast or Halo on Legendary, they'd get massacred like pigs.
I'm gonna make two counterpoints that may seem contradictory, but please bear with me.
On the one hand, Hard mode in those games is optional and is mostly for bragging rights. It's a different kind of difficulty from Souls; your enemies are tougher while you are more constrained. Your margin for error is reduced.
In Souls, you are supposed to rethink your strategy every time you die, and to look for ways to adapt and overcome. You can farm to level up or obtain more supplies, summon help, or look up the boss's weaknesses. It's not just "brute force harder".
On the other hand:
They're too comfy with fighting bosses whose patterns they can figure out and counter.
The same could also be done in those games. You just have to observe your enemies and change your strategy accordingly. It can apply like in Souls, but unlike Souls, it's not baked into the game.
ETA: personally, Souls also gives me a Captain Ahab-like desire for revenge on aggravating bosses that other games don't.
(I'm on a Souls kick right now, so please forgive me if I sound like a pretentious git).
I will readily admit, however, that Souls games are not immune to arbitrary and unfair crap. DS2's input lag, and every game's penchant for enemy attacks that clip through walls counting as hitregs, make me scream like a crazy person.
