Say Steam if you must, but please, let's not turn this into yet another debate about it. And no bashing on previous games either, you can dislike a game and still be civil about it [/backseat moderating]
For me the only thing i can think of would be not having playable beast races, as for me that is one of the things that sets TES apart from other fantasy worlds. Still, seeing how they have been playable in every other (main series) TES game, i am not worried about it. What about you?
