The game hasn't aged well, clunky movement, tile-based maps and crappy items that need constant repairs. The only good quality is atmosphere: but only tristram, catacombs/church levels have this dungeon-crawler aesthethic with labyrinths and closed doors, the caves and hell feel kinda weak in terms of level design and out-of-place. Both d2/d1 are loot-centric potion fests that have more inventory management than actual combat.
