I have successfully beaten all Larian games so far, from the original Divine Divinity to Original Sin, most of them on somewhat higher difficulty levels (where applicable).
With D:OS 2, all I get is frustration. I don't have three hours to figure out how to solve some impossible seeming fight, I have a live, too. The frustration level has risen to a point, somewhere on Reaper's Coast, that I have stopped playing. I doubt I will care for another Larian game - they only get more difficult without improving much of anything else. Inventory system and crafting is a bad joke, quests are buggy as hell. Story is meh. Perceived difficulty compared to D:OS 1: plus 250% - and judging by the release notes, they are still in the business of making the game more difficult.
Sorry, this is niche geek gaming only - for those that have unlimited time to invest to endlessly fiddle around with one unbalanced fight after another. I am out of here.
I teach at CS at a uni, here is what I tell students that simply cant seem to figure out concepts in certain classes.
People are not the same. Period.
What you might call hard, i call completely trivial. In fact, I cant play certain genres like 1st person shooters, and console games (generally speaking) because they are so easy that they might as well be baby books. To me, DOS2, is intermediate at best. Easy after the initial 5 levels of figuring things out (didnt need a guide except for boring stuff like figuring out recipes which I ended up not using anyway). This game does not throw any wrenches at you. The only difficulty was measuring when to shop for new gear. Once you figured out the scaling, it was just a matter of making adjustments.
Its simply a matter of how you problem solve. Not everyone thinks the same way. You can teach yourself to think differently, but if you dont want to, then that is fine since this is just a game. If this were a classroom, I would tell you to suck it up, study smarter (not longer), or change majors. For the record, I am not trying to be mean, in fact, I really care about students but sometimes the best advice is the cold hard truth. Not everyone is cut out for sciences (though I will argue that anyone with a healthy brain can do it with enough diligence). Also for the record I have very few drops even in hard stuff like algorithms and data structures.
Since this is a game, I would say "95/100 games are made for casuals...". there is no shortage in selection. Or play an easier mode. Or download some mods to make it easier.
