Ultimately, Alliance’s appeal lies in the variety of choices it can offer its players, both current and prospective.I understand that I am not the majority, but I don't think things need to be mechanically the same. I believe the mechanical differences and restrictions create just as much fun as the thematic differences because those mechanical restrictions feed into the thematic ones. I don't need to have access to everything in the game to enjoy it. The restrictions can be just as much fun as the having and if you pick a race that has a restriction then that is the kind of play you should expect. Taking away these restrictions and making them simply thematic choices takes all the punch out of them and I think that is bad for the play and for the representation of the race.
As a result, mechanical limitations take away from the game, even if some players feel there’s added flavor because of those restrictions, because they limit options. It might make your game better, but it definitely makes others’ worse.
