Your Feedback Needed for Visual Novel Game Design (part 5)

My last line of questioning involves relationships in a Visual Novel. There are going to be a lot of interesting relationships among the Solar Echoes alien characters, and how they interact with each other will be one of the core elements of the game. You'll need to navigate the different personalities and cultures to succeed at your mission, and I have a lot of ideas for how I'm going to make this fun, intriguing, and challenging! However, one aspect that is very popular in Visual Novels (and usually helps sales if present) is romantic relationships. This is a small problem in a typical Solar Echoes scenario, because even though 5 of the 7 aliens do have binary genders, only 3 of them have discernible differences between gender (and you'll only ever see a Chiraktis male—the one female is the Queen!) I also don't want to have cross-species romances going on, especially since many of the alien races are similar to animals we're familiar with. However, I do have some plans to include a few extra characters of the same species that could become romantic interests of the main character. A few final questions for you related to this topic:

1. Would you be happy with only 1 romantic option in the game, and have the option not to pursue romance at all?
2. Would you prefer 2 or more romantic options in the game?
3. What other ideas do you have for romance in the game? (Keep it PG—I'm not putting anything R-rated into this game, especially because I want it to be marketable to kids as well.)
