Just today I decided to not play The Binding of Isaac anymore.

I played this game for years. I unlocked everything in Afterbirth+ which isn't an easy feat. You have characters like The Lost with no health and instant death. I got through everything and beat Delirium with every character and what not.

Then came the Repentance DLC along. I got that maybe 4 weeks ago and was thrilled for all the new stuff. But the alternate path is just too much. I died 30 times in a row. Got to the final boss, mother, a few times but couldn't beat it. You get hit so often with no possible way to dodge. You get hit by stuff you can't see. You get way less health than in AB+ and the enemy projectiles fly faster than before.
It also feels like you only get shitty items now. Not even one time did I get the Guppy tranformation. Not one single time did I get brimstone. Nothing. Oh, and brimstone was nerfed because the devs hate the players or something.

I can't beat this crap even with Isaac so far. It will only get harder from here. Trying to beat the game with The Lost or The Keeper would be a major pain in the ass. It is possible, I know that. But you basically just wait for an OP run and die countless times in between. That's not my understanding of fun. So I won't touch the game again, it's pretty much dead to me. Which is a shame, because otherwise the DLC is sweet. The new graphics are great, the soundtrack is great, I can't complain. But all that is useless when the game itself isn't fun anymore. And it's not like Isaac was exactly an easy game before. The devs overshot the difficulty big time.

Rush 'N Attack, Contra, lots of NES games actually. These days with time to play at a premium I own more games that I've never played than games I have beaten.

Dude, you GOTTA play Bloodborne! IT's genuinely one of the best games ever.

Don't let Dark Souls II's cheap bullshit turn you off Bloodborne and Dark Souls III. I'm currently in a gauntlet with two of my buddies, we did Bloodborne together and LOVED it. we did Dark Souls III together and LOVED it. we played Dark Souls Remastered together and liked it a lot. Then we got to dark Souls II and...we all hate it. I knew I hated it prior to this but deliberately avoided ranting about it just in case they liked it. It's a divisive game, and while I hate it there are others who love it so I was actively avoiding tainting their opinion of it prior to starting. 

Within an hour, both of them were already like 'this isn't hard, this is cheap. Every design decision in this game seems to be there to frustrate and annoy, not be an obstacle to overcome' and as we've played that opinion has only gotten stronger. We're only playing it out of spite, now. we're not playing the game to experience it, to get a sense of accomplishment, we're playing it to destroy it, as if to say 'fuck you, you won't defeat us'. At this point we're playing to conquer it, hating it every step of the way, mockingly going 'hnuuutrrrr! Look at me, I'm Dark souls 2!  look at those hit boxes! Look at how many stupid fucking enemies I can aggro all at once! Look at how fuckign dumb it is that we have to constantly balance each other out just so that we remain at a similar soul memory level!"

The whole game is cheap bullshit with the worst bosses and gameplay mechanics. don't let Dark Souls II ruin III and Bloodborne for you. They're both like the original but more refined and with slightly different tweaks. it always disheartens me to hear of people who gave up on the series because of how bullshit 2 was. 

2 is the game that I died in the least, I found it by far the easiest of the series....but I got more frustrated with it because the deaths almost never seemed fair. I got more frustrated with it because I died due to poor design or cheapness, not 'I didn't learn from my mistakes' like in other games. 

Here is one of my deaths from last night's session: 

Meanwhile, here's my first ever attempt at Gael: 

That Gael fight is WAY harder than anything in Dark Souls II, but it was fair and with good reactions and planning, I beat him. There's a world of difference between these two experiences. 

Now you mention NES, I'm sure I've quit a few when I was a kid, just can't remember them, memories about NES are fog to say the least and the system was already dead for a couple of years when I was still a toddler. Need to check an SNES list though, these I can remember

Yes, loads of times.

That doppelgänger battle...

Star Ocean: The Last Hope.

Enjoyed the game, story, characters, set-pieces... Got right near the end where the difficulty jumped 100x... And I couldn't be bothered to spend the time grinding just to finish the game so I gave up and started playing something else.

Not as an adult, no. But I have put many on "pause". Sometimes that pause can take years to un-pause. But it always gets un-paused eventually and beaten.

Lost Levels.

What the fuck was Nintendo thinking designing that hot bullshit?!

The original Kaizo Mario!

First game that comes to mind is the original Rayman, found it super frustrating when I was young, and I'm not interested in going back to it anytime soon.
