Stories have ruined gaming IMO. Companies think they can lure in the casual crowd by making an emotional story with little to no gameplay.
This spawns the sissies saying "HURRR, BEYOND TWO SOULS IS THE GREATEST GAME OF THIS GENERATION, IT HAS AMAZING STORY AND GREAT CHARACTERS, GTA V SUXX IT HAS A sh*t STORY AND IS OVERRATED AND IS FOR LITTLE KIDS AND IM A MATURE GAMER"
I was going to say almost exactly the same thing, and hate those story whores (yeah I said it, get over it) thinking that they are so mature and tells people who like great gameplay to go and play CoD.
I've said it before and I will say it again, I like a good story just as much as the next person, but if the gameplay sucks, the entire game sucks.
Take Mass Effect 2 for example, it has great story and characters, but the combat feels like you are playing with super-soakers and pea-shooters and the level design is nothing but undetailed, poorly designed, and repetitive corridors which are filled with chest-high walls which are unnecessary and are out of place.
Metal Gear Solid 4 is another example, it has a great story, but the gameplay to cutscene ratio is awful, the 'game' has 16 hours of cutscenes (and some of those cutscenes are the length of movies) and only 4 hours of gameplay, the worst part is that Kevin VanOrd on Gamespot claimed that the game had a "brilliant mixture of storytelling and gameplay", yet anyone which a crayon shoved into their brain would know that is nowhere near the truth.
Heavy Rain (and Beyond: Two Souls for that matter, even though I have not played it) may be new concepts, but they share the most common problem with the modern gaming industry, which is sacrificing gameplay for storytelling, it does not matter if your games concept is original, if your gameplay is boring, your gameplay is boring, end of story (pun intended), those games have you doing stuff like brushing your teeth and washing up after dinner.
Overall,storytelling is usually done in the form of cutscenes, and those can usually be skipped, but you have to endure bad gameplay. Storytelling can't make a game with bad gameplay fun, but great gameplay can make a game with a bad story fun.
And to end this rant, GTA V has yoga, yes we know, you don't have to keep saying it, yoga is boring, but it's a tiny little insignificant part of what I consider to be the best game ever made because there are so many other fun gameplay features, so stop complaining about. Heavy Rain has you repetitively shaking a controller back and fourth to simulate brushing your teeth, do people complain about that? no, of course not, because it's a story driven game. If people keep giving story driven games free passes on bad gameplay issues, there is going to come a time when every game has a cutscene to gameplay ratio comparable to Metal Gear Solid 4 and the quality of that gameplay will be comparable to Mass Effect 2, when this happens, people might actually start wanting gameplay back and will start complaining about the lack of it in games, but they will only have themselves to blame.
TL,DR: Read it, it's a forum website, you should be expecting to read long posts.
