quick question. is there away to make Jean best friends with rogue or Laura or is that something still in development. right now they are good friends with jean and want to know if i should just grind out pool time with them or if that is just a waste.
No, there isn't a a way. This is statically define in code. Basically, Rogue and Laura are best friends via plot, any other combination, if I remember correctly, can only reach good friends.
Short answer: Game-wise,once you've reached good friends,you're good for any game requirements/criteria
Long answer:
Every character has a friend value, range and definition for every other character. The way it's calculated is if, for example, Rogue's friendship value with Jean is 40, and that's the top of the range,it's considered tier 1. That tier is then checked with the tier definitions. That definition determines if it's good friend (1), best friend (2), etc.
Last I checked (yesterday, I added that as part of my cheat injector), the max tier definition for most character to each other is 1. Rogue and Laura's is 2. That's also to say that Rogue's friendship value to Jean can be at 1000 and they'd still be just "good friends" while Rogue's friendship value to Laura can be 50 and they'd be considered best friends.
