Approximately how many hours did U3 have?
It's hard for me to judge, because I do a lot of site-seeing and tend to take more time than an average player. I also tend to start 3rd person games at hard difficulty, instead of normal, which ends up taking more time, as well.
12(discluding the replays) of uc2
9 on uc3
so TLOU (regarding 'easiest') about 15-20+
I'd love it to be like FF13 (72hours)
small fact you may not know;
the person 'leading' the making of TLOU, was the same as UC2 but it wasnt UC3
they split ways at the begining of TLOU development
