Someone made a really fitting picture of level design in the Dark Souls games.
i feel that's a dumb jokey way of representing 2
there's a lot of optional sections in 2
I beat every souls boss in coop unless there's absolutely no one to help. I like doing the levels myself and summoning just for the boss. Best moments of souls games for me are those moments. It's one of the reasons I disliked bloodborne so much, the coop system there ducking sucks. Though I think the covenant update helped fix that. Since that adds I think a easier way to have people join you and actual NPC summons as well. Since originally the game was super lacking in them. Like someone forgot to put them in there.
Funny enough though I played all of DS1 offline and had a good time still. That game did a great job of making you feel like you were online even when you weren't.
for me the game has never been properly balanced for coop
boss fights are stupid easy if you can divide the boss' attention, so whatever sense of accomplishment you get for defeating a boss with a summon is gone for me
i've done it a couple times on boss fights that felt unfair or unfun for me, but that's it
abyss watchers solo left me elated and shaking and full of adrenaline, those guys were scary and tough and killed me like 10 times, often being 2 or 3 hits away from defeating them. having a buddy there to just make the fight trivial ruins the whole experience for me
i stopped putting my summon sign to practice anymore either. i wanna go there and risk something every time i fight, even if it's a 1 minute run to the boss, it's super important to me
to each their own but i feel like coop makes some of the best stuff about dark souls very lame. boss fights aren't the only cool thing about dks but it's one of them so i wouldn't want to spoil that
