This is an interesting thread.
SInce developers know how many people actually finished a game when they played it.
A lot of people attribute sales to quality but I wonder what the % finished is for high selling games.
Is there a site that collects/mines achieve data?
I beat about 75% of ps3 games I bought. I never beat games like Enchanted Arms, Dante's Inferno, some Rachet and Clank game and Demon's Souls.
I also never got passed world 3 in SMBW
