Half-Life even though Valve gave up on it. Half-life series offers the most varied and fun game play with a well integrated story. It's a shame we never got episode 3 nor HL3. Shout out to Resistance 3 for its very half-life like campaign and fun game play. Too bad the first two entries don't really match up and the series was abandoned just as it got good.
Kill zone is a good series with great set design.
Max Payne is awesome, loved the 3rd entry after waiting for it for many years.
Wolfenstein the new order was great, but I didn't really enjoy the other entries in the series apart from Wolfenstein 3D.
The only Halo campaign that kept my interest was Halo 4. I never finished the others, great multiplayer, not so great single player or rather very repetitive single player. Doom also lost my interest. I enjoyed to slower pace of Doom 3, the new ones just feel like battle arenas. I need some exploration and story in my FPS games. I rank Far Cry and Bioshock over Doom and Halo.
