Nox vs Commandos: Behind Enemy Lines (2D game engine)

Just started playing Nox and wow, am pretty amazed. Fantastic game, a game that has sound effects from Dungeon Keeper, and Lands of Lore 2 (another great Westwood game!)

There's one thing that strikes me and that is the close resemblance feel of the 2D game engine. Has anyone else felt the same... that it uses the same 2D game engine as Commandos: Behind Enemy Lines? It just feels & looks so similar! If it is, then it's not created anywhere where there's Nox Wiki/pages....
