I have over 500 hours in a Tales of Symphonia savefile, but ive played the other Tales games extensively, so i should have about 1100 hours in the Tales franchise
There are a few games that might top that, but they either not tell you your playtime, or i don't have my files anymore, Oblivion should take the cake if i could see my playtime
And while it doesn't come close to those 2, ive played the 2d Castlevanias a lot, i have at least 50 clocked hours in each of the Ds ones, that doesn't count resets, deaths and such, in Cv Hd, i have 80 hours on my main character alone
