>>16Someone who didn't play Diablo.
Diablo items are unidentified by default(magic/unique) and you need to cast 'Identify' or pay Decard Cain 100 bux. Diablo2 also has this system.
identification (which might be the most important part of Nethack, while fairly trivial in Moria-likes),
Diablo NPC sell stuff, tell lore and give you quests.
interactions,
90% of Diablo is this, separating good loot, using ground to store mediocre stuff and managing inventory space(even in battle..potions can run out, 99% of combat is dependent on correct potion management)
inventory management.
Diablo2 has fairly advanced for its time item modification system: socketing, enchanting, transforms(cube recipes), a primitive crafting system.
Diablo and its successors are item-centric games that put inventory and equipment above everything else.
My advice, download diablo1 iso from archive.org and play it to hell difficulty once. Its the most influential RPG in the genre.
Everything turn-based snobs hate about "click&loot RPGs" and "FPS-like gameplay" stems from Diablo(modern dungeon/maze crawl) and its more popular brother Diablo2 which emphasized fast open-world combat(modern open-world RPGs).
