*snorts* the only reason it "caters" to a "Dovah" is due to the fact that this DLC is being released in regards to the Vanilla version of the game as in no mods like "alternative life" or whatever its called and others to mess with how the game was meant to be played in regards to this.
No you dont need to be BUT it is assumed when you are shout and people do start hinting at it right after you kill the first dragon (the guards that come with you)
No there isn't but since they added new dragons they decided it SHOULD be, I mean otherwise you don't get to see those new dragons and possible get new shouts with who knows, it could cause you to stop the DLC if you need a certain shout to continue. They didn't HAVE to make it this way but it is there game thus they did and complying about it won't stop that well except someone who makes a mod to break it thus causing u to not be dragonborn n shout.
Mods don't have anything to do with this. It's about what and how one chooses to play. That could easily be without being "Dovah". I don't think the DLC is centered around the PC being one anyway.
But as long as you are enjoying your shouting Dovakinn...that is what matters. I assure you I am enjoying my characters just as much....mod or no mod.
why should you have beaten the mainquest? i don't know, to get teh achevements, plus its been out since november, so why would you buy a game to not try the main quest?
and you don't have to be dragonborn to shout, but you do to learn a shout without years of intense training
People play TES for different reasons. Some play for the combat and run through it as any other game. That is all they see.
Others play through the MQ for getting an achievement, but those things are absolutely meaningless to most. If that is your goal, then I wish you well.
Yet others play TES as a heavily RP experience. creating different characters with different personalities and only going somewhere if it would be fitting for that character to go. Just because you know the Super Uber Duber Sword is in the Smelly Bottom Cavern doesn't mean your character does. They only choose dialog and react to NPC the way that character would. The do things that are fitting to that character.
And they do not do things that are not fitting...like being Dragonborn.
