Hypothetical sitation: you are joining a new campaign in which all other factors are positive (you know the GM and group, it's in a setting you like, whatever) but there is one hitch: race/heritage/species is cosmetic only.
So, assuming it is a very open setting in which pretty much any reasonable humanoid species is available, but none of them have any mechanical effects (including size, vision and movement types; everyone, including humans, are basically human mechanically). What species do you pick for your character?
Would race being cosmetic only be a turn off for you?
