I have only had the chance to watch reviews of the game pack. I'm not sure if adults/YA can gain character values, considering this is a parenthood game pack. I honestly like the idea of older sims still being able to gain these values (think of the fun a first generation sim could gave defining themselves and learning who they based on there value progression).
If this could be a perminate feature one day, it would lead to a type of self improve for sims created as YA or older. I am thinking about creating a poll to see how many simmers would like this feature. Until then, please say if you agree or disagree with this idea. Thank you!
