When you ask for something without ‘grind’ I have to ask if you know what you are asking. Grind is entirely subjective. It’s not a mechanism of a game but rather what happens when you personally don’t find a game mechanism fun/rewarding.
Take classic examples, like mining in… most games, really. It’s smacking a rock. It doesn’t have much variety. For some people, they love their own little game of ‘hit the rocks in the most efficient way,’ or they like to relax with music and bust rocks, or they feel like every rock is a loot box. Other people hate it for being too complex to automate and too simple to feel engaged.

The difference between ‘grind’ and an ‘endlessly replayable part of the game’ is how the player looks at it. You are asking for ‘the drug to which you will never build a tolerance.’

The first time to experience it, it’s amazing. Each time after that, it’s a disappointment.

Did you read those papers you signed when you started your job? You probably agreed to this there as well.

This would make a great little lore item in some RPG to explain why there’s a spell list.

‘We have literal magic that can raise the dead and move us across the world in the blink of an eye. Why the fuck am I having to do dishes by hand?’

‘Because no one actually knows how the spells we have work. We just have these spells left over from when they did, and ‘clean dishes’ isn’t one of them.’

Why would anyone put up with the attack that is advertising? If it requires you to watch ads, it’s not worth it. You wouldn’t sit through a free movie if it meant a stranger showing up every few minutes and offering to let you rim them, (it’s not that no one wants what their offering, it’s that they don’t care whether you’re interested or not. They’re still going to show you their asshole) why would you allow a similar violation of your mind?
