Call of duty 4, Gears of war, Far cry 2 and the best one is Metroid prime 3.

Those are the only 4 fps/tps games I played this gen and they were amazing :)

I know I put mine in no particular order, but you have RFOM ahead of Gears 2?  Seriously?    Everyone is entitled to their opinion, I guess.

@ kn

While Gears 2 is alot of fun, the story is pretty good. I thought the R:FOM story was much better. Especially since there was incentive to play through a second time with new weapons. The characters also seemed more interesting, despite Hale not saying anything. Plus the narrated story was a nice touch.

He stated "in no particular order".

The problem is that I have at most played 15 of these games, so I'll just make a top 10, in not that much of an order. Also, have you not played Uncharted? I'll assume you haven't so that I can include it

1. Uncharted
2. Call of Duty 4
3. Mass Effect
4. Gears of War 2
5. Rainbow Six Vegas
6. Resistance: Fall of Man
7. Rainbow Six Vegas
8. Call of Duty World at War
9. Killzone 2
10. Gears of War

1. Enemy Territory: Quake Wars
2. Far Cry 2
3. STALKER: Clear Sky
4. STALKER
5. Bioshock
6. Halo 3
7. Dead Space
8. Call of Duty: World at War

Here are mine in order

1. Uncharted
2. Bioshock
3. Call of Duty 4 Modern Warfare
4. Killzone2
5. Resistance Fall of Man
6. Resident Evil 5
7. Gears of War
8. Halo 3
9. Resistance 2
10. Gears of War 2
11. Dead Space
12. Battlefield Bad Company
13. F.E.A.R.
14. Dark Sector (I personally liked it)
15. Brothers in Arms Hells Highway (I loved it though most didnt)

You say this gen (which implies consoles) then have FEAR, so I'm just going to go with console/PC.

1) Half Life 2
2) Bioshock
3) STALKER
4) FEAR
5) Uncharted
6) Resistance 1 & 2
7) COD 4
8) Killzone 2
9) Gears 1&2
10) Fallout 3

Add in Rainbow Six: Vegas.

Its got a good single player campaign, plus terrorist hunt. Both of which can be done by yourself or splitscreen.

I do wonder how anyone can put COD4, Gears 1+2, Resistance 1&2, Halo 3 and Killzone 2 above Bioshock in an ordered list, particularly when based on campaign only.
