Other because of the fact that there are a few things that are not covered by the options. The plot holes are a major, as well as the unclear instructions and horrid dialogue. But its actually the atmosphere that is created. Alot of games are missing the storyline that has the drive behind it to make it actually worth playing, even games like COD:MW2 have a storyline that can be engaging to players who find the time worth to play it (though the story in MW2 is still horribly boring when you cut down to it, but it has some drama ripped from the first one, like three times infact. A good example is that of Final Fantasy VII, where the plot is dark, you can feel the desperation of the characters to do good and to save the people, but like I said it was dark, if everything had appeared as sunshines and rainbows and they were doing it because they wanted to sell cookies to Rufus Shinra you would just end up turning the game off or giving it to your child because you would just find it boring and uninteresting.
On a final note if the storyline has you do some stupid events such as you have to get like 12 flashing lights sequenced in order to progress through the story further and they flash quickly, thats just a dick move.
