You should make some scenes play a bit differently if you choose the new game+ (ie: you could drain kiss rinny's tail when you meet her, you can skip cassie because you already know where the city is, etc)

I'd rather not force players to do a NG+ to access content!
I think they mean, like, easter eggs. Things that only happen in ng+ or ng++. (Think of MGQ to MGQ ng+.)
