QFGV suffered from something similar to Leisure Suit Larry 4, although slightly less so (since there actually was a game at the end of the process). It was intended to have online capabilities, with up to five people participating in the same quest and competing against each other to finish each objective first. Obviously, that got scrapped along the way, and the game became a single-player experience with NPCs filling the other four slots. At least, that's the story I remember, and you can see it in how the game was designed, particularly the early parts.
