I don't know if anyone else needs help with this problem, but I will put in my input.
First I'd like to thank Ayden for getting me thinking about this kinda thing.
also a question for
...... I was wondering how you set up your event process?
Now for my 2 cents.
I was think that you could create a var. that was named (XXXX) Romance_lvl.
(XXXX) being the characters name you'd like to woo. Female/male.
You can then have the variable be between the numbers 1 - 200. 100 being the middle point where the char_(XXXX) is in love with your main.
A idea I had was to have a obsession range. This, instead of boost stats it would create the relationship as a distraction rather than a benefit, such as you could set char_(XXXX) hit percentage lower so that they miss more.
This could be achevied by making the var. Range between 101 - 200 be the range.
Now that the var. is made you could, in the events you want, create it so it adds to the var. a X amount of Rp (romance points) depending on the choice.
I don't know if that helps any, but its just a thought.
