(OK I'l spoiler for the people that still wants to play Follower)
In any case, back to NCC.
NCC is much more choice driven then Follower. For instance Kirsten now broke up with you and she moved in with Maude.
You can decide to ignore her completely or try to win her back. It's completely up to you. Basically you can go for one girl, all the girls, some of the girls or none of the girls. And your decision to go for a girl, does not guarantee success. Some will fall for you, some will reject you and some just want to have fun with you.
So in terms of comparison between Follower and NCC, I would say, if you survived Follower, NCC will be much easier.
There is much less "NTR" type content in NCC, in the true sense of the word. Just remember that you do not get all the girls and you will be good.
