For me it's not the best cause it's just unrealistic to sleep with everyone around without much consequences. I prefer to do multiple routes in which the MCs develop in certain directions and then choose only those relationships that correspond well to it.ooo I think I found the best routes.
Ian: Collect wit, and piss off the boss to get the will point. First time out to Shine hit on Cherry, bang her. On Wednesday go out to dinner with Alison, use the will point and bang her. Then go out with Cindy to the photoshoot. Then at the club night don't have Perry come, and bang Emma. And you still get to finish off Lena.
Lena: Be good with Robert but don't spend the will point the first time. Bang him anyways after. After good date with Ian call Robert bang him. Then at club spend the will point and bang the DJ. Still get to bang Ian.
