I've spent the most time with the Total War series. Reaching 200h on Shogun 2 and Medieval 2 and already over 150h with Rome 2. Empire Total War and Napoleon combined are at 100h.
As a child however I did play a lot of Need for Speed Underground 2, C&C Tiberian Sun, Generals, Age of Mythology, Age of Empires 2 and Rollercoaster Tycoon 2 but I have no idea how many hours I've spent with those games. Could be around 100-200h each as well.
Killzone 2, Killzone 3, Battlefield 3 I have at 150h each. Uncharted 2 and 3 around 75h each. GT5 as well I guess.
Pokemon Silver and Ruby around 60h each (I remember the savedata and usually played it twice)
The next game that I'll get to the 100h mark will definitely be The Last of Us (PS3 and PS4).
Most played genre: RTS
Favorite genre: RTS + Action Adventure
