Just to point out DA2 uses gender checks, as does ME3.
For a good romance you need gender checks so that both dialogue and interactions between the toons remainrealistic.
As an example how removing gender checks can lead to physical humour I only need to point to the modded ME2 romances, due to the different height of MShep and FShep all scenes that require interaction look weird ranging from simply bad (Miranda) to hilarious (Thane).
Umm, this is the worst excuse I have ever read yet, the obvious solution here to make such cutscenes not look weird would be to not limit the height of all female characters to a head shorter than male ones in the first place
. There's absolutely no reason for that other than trying to enforce the stereotype that all men are taller than all women which is simply not true. It's very damn annoying that the tallest, amazon-like, female character is actually.... A full head shorter than the tall male one.
Neither are "the norm", obviously, so why the hell put in that limit other than sexism.
