The difference there however is you are already playing Shepard. You are a colonist, an armed forces space brat, or a street rat running with a gang. You are a war hero, a brutal butcher, or the sole survivor of a massacre. You are NOT creating your own character. I played ME and ME2 through one time for each class. I'll still play once in a while, but not anywhere close to how often I play Skyrim or even Morrowind.
I don't feel discriminated against. I feel really restricted. I won't be able to play the way I want; the voice may not fit the character I want to build. The restriction of starting from a vault is part of the game I can deal with, just like the tradition of starting the ES games in jail. You still make your own character however. You aren't playing a preset character like Shepard. Or Hawke. And you did miss the protests when people found out that DA2 was going to have voiced protagonists and the "Wheel of maybe close to something I might want to say" dialogue. The voices and the wheel are part of the reason I never bought the game. I'm not really looking forward to FO4 at this point. I will get it eventually, but compared to the literal hundreds/thousands of hours I've put into Morrowind, Oblivion, Skyrim Dragon Age: Origins, NWN, and all of the other unvoiced games I play, I'm looking at limited replay value because of the voices. No matter what character I make, If I make the same dialogue choices, I will hear exactly the same voice and inflection. Why bother to play it more than once?
