True, D1 involves strategy and resembles traditional roguelikes, yet its tactical breadth feels limited..

So in absolute comparison to other roguelikes it's all mere coating, even on the tactics / strategy side - it tends to be more about positioning and resource management.

This is a highly subjective take of course and its appeal varies player by player..

I'd be in full agreement that Diablo 1 is the "most worthwhile" of the Diablo games and I do have a love / hate / on / off relationship with it (really glad that I'm not a smoker).
