Finished this weeks podcast.
Would something like Zelda be a precursor to Diablo? Sure it doesnt have that loot system but you have a top down view, A overworld, multi level dungeons.
In some ways, sure. The thought did cross my mind during that section.
However I think the loot is so intrinsic to the Diablo experience that it allows Diablo to stand apart from something like the 2d Zelda's. And especially as it is a part of a larger set of idiosyncratic systems (action rpg combat, character levelling, randomised dungeon crawling etc.)
