1st page sounds like it's describing every/any rogue like. end goal/boss, random generated levels, lots of race / class combos, turn based gridded movement, increasing danger with depth, improving characters, magic treasures to improve player capabilities.
Maybe I only played DII+, but that doesn't sound like much like diablo that I remember. esp turn based?
So glad they dumped the turn based stuff! I've played through both I/II (prefer I) and it has some of these features. If I recall correctly the movement is somewhat grid based (but enables the player to move in more than 4 [8?] directions).
I read somewhere else about the move from turn based. If I recall correctly (sorry, no citation), the game was feeling a bit static, pretty much as you described. Somebody built a prototype live mode and that was when the game started feeling good.
