I'm curious how these scores affect the ending. Do you need characters with identical traits to get the romance ending? For instance, in my play-through the two protagonists had pretty much the same traits, differing only in pragmatic/romantic and spiritual/materialistic axes and although there were plenty of R/P/S instances I resolved all the special banters (friendly fire, soloing, sneaking etc.) peacefully. Yet in the end they went separate ways. I would have thought the latter, the so called "affection", would have bigger impact on the outcome than "affinity" because if couples couldn't overcome some minor differences, humanity would have gone extinct long time ago. Any thoughts/observations?
