Well, original poster, the thing is that there exist players who want to have choices that demonstrate noticeable differences in the way the story plays out. Frankly, your whining that you have a short attention span, and can't tolerate not getting the entire game because those differences exist, is just annoying to these players.
Maybe you need to stop being so shallow about how "your gaming is seriously ruined" by developers attempting to provide what players have been wanting for decades? Maybe learn to stop being such an instant-gratification demanding sycophant who wants developers to simply dump the entire game in your lap, perhaps like some kind of non-interactive cutscene where you can ooh and aah over the pretty graphics, in their entirety, without having to worry about anything you do within the game stopping you from missing a pixel?
In other words, no, I don't think you are playing it right.
However, I endeavor to be fair. So, to scale it back a bit, I'll just say that different genres suit different audience niches. Apparently, your preferred genre is "really shallow RPGs where choices aren't influential enough to justify their own content." Also known as completely linear, non-open-ended, games. Good news, there's no shortage of those games, and I know this because I'm continually confronted with them and I think they suck.
Stick with those, keep your peanut butter off my chocolate, and we can exist in harmony. Alternately, you can change the way you play games enough that more developers can be encouraged to advance the state of computer RPGs, but I'll not force you.
