Are you just guessing or what?
Because typically NG+ modes are just "the exact same game but everything has higher levels and you'll start keeping everything you had at the end of the previous playthough.
Which is usually complete garbage.
"Hey, it's even easier than before and with less things to do! But now with BIGGER NUMBERS!!!"
Man, I so hoped that the rumor was false and we were getting some hardcore mode or similar, instead.
Yeah, I'm guessing.
I'm hypotetically saying what would be a good NG+ mod.
