Halo's plot is completely childish, and is no way innovative or interesting in the science fiction genre.
It's like saying Avatar has one of the best plots of the science fiction genre.
I don't see where he said it was innovative. The appeal of Halo is that its half-homage, there's a lot of references to other sci-fi (the movie Aliens for one). No game has an innovative story that isn't ripped off from other work, but that doesn't mean they can't still be good. I didn't really find the overall story of the Halo games to be that great, but you seem to be looking at them as wholly serious. I view, at least the original game, as sorta like Hot Fuzz, in that it actually has its own serious storyline, but it draws from the genre and pokes fun at it and itself both.
I'm talking specifically about the first game. The latter games, as I explain later I find to be disappointing.
This.
Diablo is overrated. For that matter, so is Starcraft. Once you get a pattern memorized (that some 12 year old Korean probably figured out years ago) theres not much thinking any more. I noticed I started doing the same thing with Age of Mythology recently. There seems to be a good system for each race, regardless of map type. If executed properly you can always win. No more thinking. I grow bored.
Thats why I like my wargames. Grid based and such.
Always thinking. Brain is stimulated. I dont fall asleep. Fun times.
Various games appeal to various aspects of your brain. If you're only playing games to appeal to aspects of strategy, then yeah, games like Diablo and tons of others won't be all that appealing to you.
Based on your posting, I have to wonder why you even bother playing single player campaigns. You've realized games have a limit in that they can't develop AI that evolves with you. In fact, I think the developers have specifically made the game so that you can always win when you figure out the method. You really should only be playing against other players if you want challenge and an opponent that can potentially change strategy. Of course some games aren't very good still, and you'll run into a wide variety of opponents, many that might not be very good, and then others that are considerably better than you, so you're not likely to be facing relatively equal opponents to yourself which can make the game frustrating (not fun to constantly dominate or be dominated).
Lastly, as far as mindless games go, especially FPSes, the funny thing is, they actually do improve your brain. Its actually a good thing that your brain has functions that implement basically free from your critical thought as otherwise we'd be dead as a race a long long time ago if we sat around thinking every single action. In fact, the way some gamers talk about utilizing spatial awareness via audio feedback is similar to how a blind person develops their awareness. So yes, it might be mindless, but don't delude yourself into thinking its brainless.
