re: Final Fantasy VII Rebirth will take around 100 hours to play through

I’ll answer your question honestly even though you’re being a prick regarding NG+ and it’s various features additions and choices

1. First you can choose to reset all quest to original or keep your progress

2. New options are added like auto picking up crafting materials and some various other quality of life stuff like being able to choose whoever you want on your date in chapter 8 and 12 from anyone regardless of your current mood with them

3. All the map icons don’t reset any you did in play though one are grayed out and treated as complete

4. New costumes are added for red and Cait with and you can change costumes anywhere at choco stages and where them anywhere in the game not just costa del sol so if you love Tifa tits good news for you

5. Various new things are added like manuscripts and collectibles not available initially and if you beat the super boss on normal (or eventually in hard but it’s in chapter 13) as mass amount of hard mode lock Vr super boss content is there including fighting Zach and Seph and much more plus just a massive amount of new hard mode specific content in VR and the various battle arenas around the game

6. You also have the option of skipping all the Zach non gameplay parts in cutscenes intercut through the game

One thing I found odd testing it it out but I started a regular new game on dynamic just to see if anything carried over and your parties XP does for some reason so I opened the game on level 10 and the whole folios is visible.

That said I’m barely anywhere into hard mode even though I did every single map icon in run one so it shouldn’t take more than 25 hours to beat

Hard is much much harder than on remake though. Seems they put in much more effort and didn’t just scale up enemychealth and damage (which they did) but the AI and movesets. Just for referencing I died 3 times on the tutorial boss in chapter one because Sephiroth kept getting one shot if he gets caught under the grab and pound. Parry and dodge windows are incredibly more precise and some enemies even have different pressure conditions. It’s pretty necessary to know your enemies weaknesses ahead for bosses and elemental your weapon and use the materia that extends parry windows. I’ve heard the zolem is the first true super test on hard and I’m saved right before it doing some work atm
