What was your most played game for each generation?

[COKTOE]

For this gen, currently at 570 hours for EDF 5. Kept playing well after getting the plat, and still going after slowing down a lot in the last month.
EDF 4.1 is easily #2 at approx 530 hours. Exact figure is a bit of a guess since I haven't been on in about 18 months, but it's a solid estimate.

Continuing...EDF ..cough cough. EDF 2025 on PS3 was over 500 as well. Probably the last gen champ.

Prior gen was Project Gotham Racing 2 on the Xbox. My most played game ever. Broke the game play clock. At 999 hours, it stopped tabulating. Probably around the 1200-1400 hour mark.
