Hmm, there a few I have 100+ hours.

Killzone 2: 150+
Killzone 3: 150+
Shogun 2 (incl all DLC/expansions): 150+
Battlefield 3: 100+
Age of Mythology: I'm not sure but I think it's also 100+
Grand Theft Auto 4: 100+ divided over PS3 (+DLC) and PC

Games that I'll probably play the same amount:
Currently:

Battlefield 4: 70h (but can't play for now since it is broken again on PC, servers, rubber banding, netcode errors etc.)
Rome 2 total War: 75h, will probably achieve it within a month since I just finished the exams and patch 9 is good!
Uncharted 3: Don't know if I still am willing to play. Did the SP 4 times, Played the co-op fully twice and enjoyed the MP+DLC, probably around 75-80 as well now.

Borderlands! I have no idea how many hours since I'm playing on PS3, but I have four toons - two in pt2.5, and two halfway through pt2. And I'm still playing! Got a lot to finish before buying BL2 GOTY and starting the loot-hunting all over again! ;)

The last time I obsessed over a game this much, I was playing Descent. Anyone remember that one? ;)

Other than that, probably Resistance 1 and 3, since I played both of them three times (once alone, and twice with co-op). Plus R1 had local PvP, so I sunk a few hours into that.

Let's see:

Over 500h
------------
Diablo II ( and Lord of Destruction)
Super Smash Bros. Brawl

Over 100h
-----------
StarCraft (and Brood War)
Chrono Trigger
Final Fantasy VI
Final Fantasy VII
Final Fantasy X
Tekken Tag Tournament
Mario Kart: Double Dash!!
Mario Kart 64

Skyrim- 150 hours
battlefield 3- 400 hours
battlefield 4- 100 hours and counting
monster hunter freedom unite- 550 hours
rome total war- 120 hours
cod black ops-150 hours
battlefront 1-i've got not clue
battlefront 2- easily 300 hours

Super Mario Strikers Charged, SSBBrawl, Skyrim CoD Black Ops and MW3, and BF3. Maybe Mario Kart DS. Pokemon is probably collectively at least 500 hours
Online multiplayer games used to suck up so much of my game time... which is why I've tried to stay away from them a little more. So I can play all the amazing single player games out there.
