I see where you are coming from. Still, I think it's those people who have problems (about who to top / who to bottom) need to learn to deal with it.
- I'm not the developers so this is guess work: most ain't really clear if their game will heading toward one position, which makes it quite difficult to add such description.
- It's not about 50/50. You make some disappointed, but others will be happy that certain characters are top / bottom.
- If the dev can make a character to have both, it's great, but that's not easy and should not be considered "Mandatory".
- If it's not a role-play game, you don't necessarily have to self-insert as MC.
But, I was talking about Finished games, or free games that you can make educated decisions. Just saw one victim in this discussion because the dev ain't upfront of their crowd-funding campaign. In these cases I do think we need more regulations of the liabilities of the development's transparency, like "what their WIP projects offer", "what you pay money for".
