I have to admit that I was disappointed in DA:I because I thought Dorian was a very good character for gay males, but was not impressed by Sera and thought lesbian characters were short-changed in comparison.
On the whole I like a game to either have a lot of romance options with defined sexualities or for them to be player-sexual if you have fewer options. There's little worse in game romances than having the only character that sounds like a good romantic partner not be an option for the character you're playing.
