Actually, there are multiple problems with this...
Game devs have limited funding and limited time. The fun route is often the best way to go if they can't get the game to feel fun and complex at the same time. Often times we end up with games that make our heads spin and we never touch them again, because while they give us a lot of options, we were looking to sit down, relax and enjoy ourselves, not study, learn and practice a fictional environment.
Games span more than one generation of people now. You'll never see people agree on this subject because one group grew up on pacman and asteroids, and another group grew up on halo and call of duty. It's a big argument between 10-20-30-40-50-60 year olds. It's really just simpler to accept that some people like easier games, because they don't have easy lives, and some people have easy lives and want challenging games, or some people live easy lives and want easy games, hard lives and hard games. What matters isn't what joe shmoe that lives 500 miles from you is doing in his living room with his games, but what you do with your games. If you need to post on a message board (basically ranting) about an argument you had with someone else, and you even need to go to such length as to curse them out behind their back... well, I feel dirty for even posting here.
I find now that I'm older I don't prefer to pretend I'm in the game worlds that I play, I'm a little more rooted in reality now, so.. when I play games, its purely for fun, not for becoming emotionally involved with pixelated people/worlds.
I just don't have the time to waste on it. So, games like New Vegas and Dragon Age Origins bore me to DEATH with their linear and bland worlds, because I don't really care how believeable that NCR dudes life story is, I'm not playing the game to (yes here is that argument) read a book or watch a movie. If my game starts feel like I'm doing that, I genuinely feel that something is wrong.
I mean, say you're reading an e-book and you turn the page, and it loads a video clip all of the sudden. Were you expecting that when you bought a BOOK? So what if it 'brings to life' the characters of the story? What if you were happy with YOUR version of those characters in your head? What if you just wanted to read a damn book, play a damn game or watch a damn movie? If the game plays like a book or becomes more of a movie, then it fails as a game, because it's AVOIDING its own purpose.
/shrug, I ranted a little more than I wanted to there, oh well.
