In an official statement on the Star Wars: The Old Republic site, Bioware‘s Stephen Reid has told fans that same-sex relationships between players and companion characters will be included in a post-launch patch.
Due to the design constraints of a fully voiced MMO of this scale and size, many choices had to be made as to the launch and post-launch feature set. Same gender romances with companion characters in Star Wars: The Old Republic will be a post-launch feature. Because The Old Republic is an MMO, the game will live on through content expansions which allow us to include content and features that could not be included at launch, including the addition of more companion characters who will have additional romance options.
