It's obvious you don't read posts in this thread, otherwise you'd've seen the one just above yours.
It's obvious you lack the basic level of intelligence needed to look at time stamps on a forum thread before making wild accusations. Furthermore I'd have thought it would be fairly obvious I was responding to you given how I kept on quoting what you were saying and responding to your posts. There's a big difference between providing a link to a side that points out some similarities between games and outright stating that every game is exactly the same. But then, you seem to have a penchant for making outlandish claims with little to no substance in them.
Finally that chart you included is fairly laughable - just playing around with the first row you can have them all different (at least for the ones I've played out of the list): BG2: You are the son of a god, a hero, and have beaten many powerful foes
NWN: You are the top student in an academy of heroes, without equal amongst your peers, trained while there to be able to save your city from destruction
KOTOR: You're the evil ruler of the galaxy responsible for many henious crimes, but are suffering from amnesia (or something similar, can't remember the precise details). Even at the start when you're not aware of the full details you're given hints that there's something else other than you just being some faceless person
Jade Empire: You think you're just a peasant but in reality you're the last child of an order or ruler or something (can't remember now)
DA: Origins: You're the youngest son of a proud noble family, and are betrayed by a family friend, seeing your parents cut down as you flee for your life
I'm struggling to see those are exactly the same. Some have twists about who you are, some don't. In some you start off in a position of power, in others you start from nothing.
What is the main similarity though? In all of them you start off at your weakest, and over the course of the game you gain skills and become stronger. What a surprise, given they're all RPGs!
I also had to laugh at one of the later points 'you have 2 companions of martial+magical prowess'. Who'd have thought - an RPG which allows noticeably different gameplay roles (i.e. mage, warrior), and then when it gives you companions it allows you to experience this variety rather than giving you a choice of 10 identical warrior companions, and no mages/rogues. That's almost nothing to do with story, and everything to do with gameplay and good game design.
With that sort of logic, 99% of RPGs are the same - you start off with few skills. You pursue some goal which ultimately ends up with either the fate of many depending on you, and by the time you save the world/city/race etc. you're very powerful. Oh and the game's final battle will be with some evil protaganist who is meant to be very powerful. You will also get a choice of how you progress your skills, and if you have companions to help you they will tend to hail from a variety of backgrounds with different roles (some may be mages, others warriors, others thieves).
