I agree with much of what was said before, and I realised that I probably made a mistake in my approach to character development (I made the same mistake in my CSComp entry, so I guess I’ll have to carry that forward in my next two games, though I hope that will teach me a lesson…)
So, basically I know I’m not going to get top scores for character development, but I want to go from a score of 10% for that, to maybe a score of 30-50% (i.e. from, “I don’t know these people travelling with me in the car at all”, to “well, it wasn’t done in the best way, but at least I feel they were people…”). For the case of some of the characters they already have a small vignette, and there is another small one when they spend time together, but I wanted to add a little bit more. I like @Szaal suggestion, about the NPC asking a random question, and then the MC having to react to it, and maybe ask something else in return, or just stay quiet. It might add a little bit more to the game, without me having to re-write the entire structure.
What other questions of that type could be interesting? Like, if the NPC asks the MC what kind of food they like, then the MC has the choice to answer, stay silent, and then possibly ask the NPC some other question (or also what kind of food they like…)
