Romances, especially equal choice romances available for both genders
And what I mean by that is, story content-wise, to have the same amount of choices and same degree of depth for romanceable companions for female players as there will be for male players.
I was both surprised and dismayed to learn that gender customization wasn't included by default in Tides of Numernera. As moving as Planescape: Torment was, it would have connected all the more to the other half of players by adding content to flesh out a story that was equally valid for a female protagonist. Considering it is now more than 10 years later and the 21st century, when most RPG games that claim high customization/interactivity and "personal narrative" are providing both gender choices by default, I'm rather dismayed that Planscape: Torment's successor had still started off neglecting its many equally passionate female supporters, myself included.
Since Planescape: Torment contained some rather touching romantic relationships, I'm assuming Tides of Numenera will be the same. The only thing that worries me, judging by the lack of a female gender choice at the beginning, is that it will continue to skimp on content for the female protagonist, such as having romances. And romances are an integral part of the emotional connection with your NPCs, which provide the weight and meaning to a personal narrative in an otherwise virtual and meaningless world (just as relationships are the most deeply meaningful part of life, for most people at least).
So please, provide in-depth romances for your NPC companions. Provide choices for both gendered protagonists, and make sure there are at least the same number of choices and all have the same degree of depth and satisfying interactivity to them.
Thank you.
