my only problem with this legacy system is that once you put a character between two others, all other choices except child or adopted child are locked. that bugs the crap out of me.... grr. no clue why they would do that..
This ^ I'd appreciate it if they relaxed the tree structure into something a little more web-like, not just to free up characters trapped between two others but also go into more details about how each is connected. My main character is adopted by a Zabrak bounty hunter but is the biological daughter of a Jedi Knight, but the two are not married, they're rivals, and I can't quite show the full triangle that is my complicated legacy family.
On another note, I couldn't resist this thread because I have a Sith pureblood and Chiss as adopted siblings.
