Every character should not have a gay/bisexual option just to please those few who want it.You need to take into account the characters themselfs.Like Alister from DAO was not gay, bottom line you dealt with it because that how he was.If games are going to become like you say then there should be a option at the beginning to choose your sexual preference.The thing with Anders was forced.I was like "wow dude thats not my thing".I check the little broken hearth response then he acted like I was a jerk.D Moness said:I found Anders less forced then Isabella she almost jumps you the second you meet her.
I romanced Anders the first playthrough because i found his character interesting in awakening (not after the climax of act 3 though).
More forced is Isabella(who i romanced the second playthrough) she is also the problem/glitch if you sleep with her for fun she will be named in the epilogue (whoever you decide to romance).
I think it is a step forward that almost all characters that you can romance are bisexual(as to the characters that are very obviously gay/bisexual)
As far as Isabella goes it proves that a women needs more then a rocking body to be attractive.I found her very distasteful and regretted sexing her up on my first play through.Her romance however wasn't forced as she openly stats that shes a whore and likes to bump uglis with anyone.
