Been playing some older games and have some times to fill in a few gaps:
Baldur's Gate (PC) - 50 hours
Baldur's Gate II (PC) - 60 hours
Splinter Cell (1st xbox game) - 18 hours
Just a suggestion but I think the 2 Elder Scrolls games should be together on the list. It is strange to have Morrowind not listed with Oblivion. Great list though.
