Ha, OK fair enough.
I was fond of Monkey Island 1, Full Throttle, never played Grim Fandango, and completely loved Psychonauts. I felt the same level of craftsmanship from the Brütal Legend world and characters, and was just enrapt every time I tooled around the world, seeing the sights, and even watching the cutscenes.
The early RTS battles were too easy to be a threat, and the last ones were too scripted to be finished without multiple retries. This is always the situation with singleplayer RTS campaigns. I think they're really meant to be played competitively.
