Both the interface (on abstract level) and the procedural generation were innovations of Rogue. Rogue even has a section of the manual which explains how was it different from other games, and it mentions both. Some sources say Rogue was the first graphical adventure game. When "roguelike" got official in 1993 (and also earlier), it was about the interface, not the procgen. The genre was not called e.g. "ASCII dungeon" because they realized that neither using ASCII or the dungeon was important. There were games before it (like Beneath Apple Manor which had both aspects) but it was Rogue which inspired them.
Electro-Mechnician is not an action game (that means games emphasizing physical challenges) and not really a dungeon crawler (no exploration, no loot, no traps, etc., and some people say that dungeon crawlers are the 3D ones...). There are lots of procgen/randomized games which do not appear to be inspired by Rogue. Games where you move and fight like in Rogue but not procedurally generated are very rare, please tell me if you know some interesting ones. (Kroz and Ultima are not that similar, maybe DROD but that is more of a puzzle than adventure.)
