For me, the availability of gender and orientation doesn’t matter much.
When playing Choice of Games (or various first-person video games) I lead my MC, who is usually someone very different then me, through the game’s world. When I replay games, I love to see how different stats lead to different outcomes, and gender and orientation are for me just two variables among many. If they matter, for example in Choice of the Vampire, I highly welcome them, if they lead to small differences, I see them as more of an easter egg, and if they don’t matter at all, they’re just a formality, just like the name selection.
Therefore, I’ve equally enjoyed Sabres of Infinity and Guinevere, just as I equally enjoyed the Hobbit and Harry Potter and The Hunger games and Divergent. I’ve also played through all of those games that I’ve installed with all available gender and orientation combinations.
Nevertheless, even before this discussion I’ve noted that many people here have a very different approach and see the MC as more of an avatar of themselves, and want them to share as many traits as possible. Since gender and sexuality are very important to define one’s person for most people, I can understand that they are disappointed if they can’t customize these traits in a game.
I think everyone has can disapprove a game for the lack of choice on that, just as I dislike certain games because of other factors, like replayability, quality of writing, setting and plot etc.
I don’t expect anyone to like ALL games published under the Choice of Games or hosted Games label, I think nobody does. I think it’s good that CoG has many different games so that everybody will find SOME that he or she likes to play.
In order to find the right games, I strongly advise everyone to play through the demo (or the WIP) before buying it, and doing this should be suggested in the game description if mentioning genderlock doesn’t work.
