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

I think 7Remake is a great entry. You are just gonna have to wait a bit to play rebirth on PC but it is still an enjoyable experience in its own right. 16 is solid. 15 is decent.

Crisis Core is action but it was made for PSP so it’s limited to the hardware but gives great insight to the FF7 universe.

If I had a blank canvas and was a FF virgin who wanted to play action combat I’d play this order:

-Crisis Core
-Remake Intergrade( FF7R and DLC)
-Rebirth(if possible)
-FF16
-FF15
-FF13 (speedier turn based)

Now if you wanted to wait until rebirth is on PC before playing the 7 universe.

Play FF16 then FF15
