I just don’t see that as a valid parallel. A nude Jennifer isn’t a common feature of movies. The common features of movies are sound, film, lighting, actors, sets, things like that. If you were to make a movie that had no sound, that might be a valid point of complaint.
Multiplayer is a common feature of video games. It absence MAY make the game less than it otherwise could have been, and I could in fact cite many examples. Of course, there are also games that could NOT be enhanced by MP, and that’s fine too. Like I said, Max Payne doesn’t need multiplayer.
No, it isn’t necessarily stupid. To use Civ 3 as an example, yes, it was “the game” as released that it was single player. But in that case, the absense of multiplayer capability was a significant drawback to the game; it’s a game that conceptually lends itself to MP play, AND virtually all similar games have multiplayer. The game was a much weaker product without MP than it should have been with it. If I’m handing out scores, I have to count that against it - just saying “well, it’s not the game” isn’t a real counterargument.
Or take graphics. I am personally of the opinion that pretty graphics aren’t really that important; like a lot of people in the thread, I’m more interested in a good conceptual game. I’d rather play Railroad Tycoon with EGA 'phics than a crappy 3D game. I’d rather play Red Baron or TIE Fighter, without 3D graphics, than EF2000, which had 3D graphics but was’t actually any fun. I’d much rather play X-Com, which had sill graphics but was a fantastic GAME, than Riven, which had impressive graphics but was not much of a game. However, it’s still valid to review the graphics as part of the package, is it not? To use an example, “Rollercoaster Tycoon II” is a very fine game, but the graphics are dated and sucky. I still think it’s a good game but it would be better with some post-1996 graphics, and a review that doesn’t say so is incomplete.
Those things can, and in many cases do, DETRACT from a game. When I buy a game I’m paying money for an entertainment product. A lack of common and relevant features detracts from the quality of that product - some more so than others, to be sure. It may still be a very fine product, and in the case of SOME games - not all, but some - the lack of MP might not be relevant. But in many cases, it’s very relevant.
