I had this conversation with a buddy of mine the other day when I posited that there must be some level of challenge (or competition) and goal to a game for it to actually be qualified as such. Maybe it's because I grew up in the NES era long before the games as art or the big casual game boom.
I don't buy into "games have to be challenging to be games" argument. You can have an easy game still be a game. There just has to be some aspect of competition, even if it's not difficult competition.
My notion was that without some kind of resistance (even token at best), there really isn't much point to playing anything. Even Solitaire has the timer and the possibly of putting yourself in a corner.
I would agree that without token resistance it's not a game, but that doesn't mean it's not worthwhile. Taken to extremes, there's absolutely no resistance to finishing a movie (unless the movie's bad), but that doesn't mean that no movie is worth watching.
Exactly why we need a better term. "Movie" still works but "game" doesn't describe what we're talking about at this point.
