What's the fun in that?
I'm not saying all RPGs do it, but it is a very, very often used character trait in video games. It is easy to find games that don't use it. I was more blown back from the amount of cliches they used at the beginning, it was a poor initial impression. I'm definitely going to finish the game and you guys have me curious to see how they spin it around into something interesting. I haven't read any of your spoiler tag stuff.
Instead of being washed up on a beach (Conan Online, Rune, EQ2, Risen, Zelda Link's Awakening), have amnesia (Indigo Prophecy, Bioshock, KOTOR, Planescape, Shadowrun, The Witcher, numerous FF games, Lost Odyssey, and the list goes on and on), or be a brain dead prisoner (all Elder scrolls including online) [HOLY CRAP, I JUST REMEMBERED THE DRAGON AGE CHARACTER IS A PRISONER TOO!!!!] give us a real character who we can learn about and possibly connect with.
With the exception of a few, all of those beginnings are really only used to do two things, make a blank character for the player to envision themselves as or artificially limit the character from knowing key information in their past so the story can slowly unravel in a contrived way. I think the blank slate is a writing fallacy to begin with. It is something games need to get away from to truly tell good stories. When we "role play" we role play the character, not ourselves. We make decisions in games that we would never make in real life, so they out-of-ourself decisions. We don't need a blank slate to cast ourselves on, because we aren't playing ourselves.
Give me a well written character to ride along with and help make decisions that I think the character would make in that world. That is roleplaying.
And if they want to use a blank slate, don't try to justify it with amnesia or being a prisoner in a new land or whatever. Just drop me into a dude on the street and tell me nothing about his past or why he's there. I'll make it up. Then start throwing situations at me and let me figure it out. That would be awesome.
Anyway, definitely a tangent. I'm not trashing Dragon Age. I'm having a lot of fun with it. This is more of a general commentary.
