"How could they include a dog in Fable II when there was none in the first game? That is so not Fable!" That's true, it's not Fable. It's
Fable II. The same goes the guns in Fable II, did you not like them either? Maybe all games in a series should be exactly the same as it's prequels and sequels.
I personally liked the dog in Fable II (and Fable III) and the guns (not to say that I did not like the bows in the original game) and I'm sure I am not the only one; when it comes to Fable III and it's wings as well. They're just optional cosmetics as far as I know (mighty power displays, how can you not like?). If you don't like them, don't use them. If they don't have any other purpose, how are they any different than tattoos in the previous games? Purely cosmetic which some like and some don't. ^^
EDIT: Besides, what's wrong with JRPGs? As long as they're at least somewhat original, of course.
