My favorite traditional roguelike was Dungeon Crawl Stone Soup. I haven’t played it for a few years, however, so I don’t know about its current state.
In recent years, I’ve played tons of Slay the Spire, some Monster Train, and most recently Into the Breach. All technically roguelites, I believe, but still scratch that same itch for me.
Hell has become much scarier than it used to be. There's a pretty cool new species that can't use spellbooks but gains spells at level ups and trains all spellcasting form a single skill. Food is gone. Many quality of life simplifications. Most spells have become a more interesting than the previous iteration of "fire blast" vs. "ice blast".
I'd say on a whole it's become a much nicer experience.
Many people seem to rage against the removal of content that felt flavorful or gimmicky or part of the tedious grind that they grew up with. I think the game has gotten much better personally. They also removed enemies that could break your consumables and inventory encumbrance limits (items, not armor encumbrance). I can't really imagine playing with them again.
Food in particular always felt stressful and time consuming even though I never made it to the end without an enormous stash of permafood.
I’m not sure about Monster Tain but Slay the Spire is not a roguelite, it’s a proper roguelike. The key distinguishing factor is that the meta-game progression doesn’t make the game easier, it just makes more of the content available. A fully unlocked StS on ascension 20 is much more difficult than the starting game.
The original roguelite was Rogue Legacy which started you with a weak character and allowed you to get stronger through multiple runs and deaths. By the end you had a very powerful character which made it much easier to win. This is the essence of roguelite gameplay: metagame progression that reduces the difficulty and rewards repeated play, helping you to win the game without having to master it.
IMO Enter the gungeon did the metaprogression without making your character stronger part really really well, would hugely recommend trying it out if you haven't and don't mind it being real time.
