First, I have to state that I have a great deal of respect for this community for the simple fact that all responses to my (decidedly negative) opinionated post were met with intelligent, respectful, and largely insightful responses. You all have my utmost respect for this!
To answer the question, to me, it is a matter of "Return On Investment" (ROI). My Investment is my time, which may vary per participant, but for me personally, my time is quite valuable. I won't go so far as to assign a dollar value to my time, but I hope it sufficient to say that I expect at least as much enjoyment from 2 hours of my time as I would expect from a relatively mediocre/good movie (opinions matter, of course). If I "play" or "try to play" (tutorial) a game for more than a couple of hours, I would (according to my "movie" analogy example) expect to be "fulfilled", "happy", "satisfied", or some other such emotion instilled by some "entertaining experience". When I won a game of AI War, I did not have this "entertaining experience" feeling. It was more of a "Thank God, this is over" thing. I had no desire to ever touch the game again. After spending well over 50 hours on the game, this was an example of a very poor ROI.
Damn, I think I've VERY MUCH over-thought this. My sincere apologies!
