It's not that they become too tedious. It's that you can't devote the time and energy necessary to get through them anymore. Which is totally fine. Play something else. Don't complain that Dark Souls is flawed because it won't dumb itself down to fit your new circumstances. It's not. It's just not for you anymore.

There is no gaming TLDR. Either read the entire article or don't learn what's in it.

I really like Souls games mainly for their clever level design and I fire them up from time to time just for some random combat. Same way I do with Severance: Blade of Darkness for last 15 years, just that latter has better combat.

But the thing is, Souls do become tedious after a while for me cause of their inherent design, even if I have some time - simple fact that I have to do same shit all over again, just cause camera fucked me up and I fell off the ledge into abyss usually makes me force quite them and pick something else. Something that might be much more difficult and time consuming, but that actually won't make me replay the same thing over and over again.

Grinding, for any reason whatsoever. Some people apparently love it, but I think it's the most blatant and pathetic of filler.

You must be so disappointed they put an elevator in Mont Blanc :) (Well actually the mountain next to it)

Video games don't need a barrier for entry like actual dangerous things eg driving around the Nurburgring. It is a conflicting game design if done poorly, that is putting up roadblocks wihout alternatives. Skill isn't absolute.

I guess we simply differ on the enjoyment of video games. For me understanding is enough to appreciate, mastery is not a goal in general. I don't play games to beat them. That doesn't mean high score attacks aren't fun, there is a time and place for everything. Inflexable roadblocks in story driven games is poor design.

I would love to walk around in Dark souls again, but yes, the game design stops me. Instead I simply enjoy my mental version which is porbably better than the actual game by now :) The level design is amazing, the environments great, did not like the boss battles or forced pvp though, and indeed those ledges! It would have been better game design if you could simply opt out of pvp instead of me pissing off other people by signing out of psn when certain functions suddenly disappear (when someone is trying to invade) If I could play it again with skip option for the bosses, sure.
Difficult boss battle roadblocks have a negative effect on the game for me. In DS2 I ended up grinding too much which made the boss battles manageable enough, yet at the same time made the majority of the game too easy. Adjustable difficulty is simply much better.

What I'm describing isn't mastery. It's competence. Someone who beats Zelda 1 after 100 deaths isn't hasn't mastered Zelda 1. They are compitent. Someone who speed runs the game without dying is mastery. Not being able to beat Zelda 1 comes from a lack of compitence at the game. If you're not compitent at a game, you don't understand it, meaning you can't appeciate it. You don't get to finish a game you are incompitent at.

Its not poor design. If you want to experience a story with no roadblocks, read a book.

Your mention of missables reminds me of the Tales games! I dunno about the newer ones, but the older ones are so terrible with this. It's soo easy to miss things, you likely don't even know it. You have to use walk thrus to find them all, I swear. They are sooo bad T_T
