From back-in-the-days till now, it's LucasArts / LucasFilm for me too.
Never liked the story nor the gameplay behind Sierra games... not to mention the early, blocky Amiga graphics... but I did love to read and view the PC version's reviews/solutions in magazines!
The only Sierra game that I've actually completed and kinda "enjoyed" was Phantasmagoria 2, cause of the sex scenes
... Damn... I even got the original from a friend right after getting me first PC just to enjoy the "multimedia" phenomenon every PC mag screamed about.
