I feel the same... I remember as a kid, being able to get kits of hundreds of just random blocks and variations and just being able to build/play... all the sets today are all custom blocks that just constrain you and often aren't significantly reusable while I'm not sure that I've even seen basic block kits anywhere in decades now.

edit: I know you can get thousands piece brick sets from third parties or random bulk set sales on Amazon... the issue is the random bits are from the current sets mostly with little reuse value, and the bricks sets are from third parties of questionable tolerance compared to real lego. I just want to be able to get a classic 1000-3000 piece set of classic bricks/pieces from Lego proper, even if it's $100-200 total, still way more than 3rd party but maybe not the same margins for Lego as the bespoke sets.

edit2: there are some "Lego Classic" sets that are closer to what I would like to see, this is probably the closest.

But even then, maybe need that many more bricks that are just bricks... again, there are third party sets that are all block variants that are much bigger/cheaper... would just be nice to be able to get more of those without paying an arm and a leg.
