Simple question: What do you guys thinks is the Best FPS franchise of All-Time...

(Note) I know there are alot more FPS franchise's out there, But i only wanted to choose the ones that are more popular and succesful to make it more easier to choose from.

Also franchise's like Ghost Recon, and Red Faction are disqualified sence they went from FPS to TPS.

If none of the games listed is your favorite franchise, Then feel free to post your own.  :)

Halo because of the things it did for shooters on consoles

So many choices but no Half-Life?

So how are some more popular and succesfull on the list then Quake and Unreal?

My vote goes to Half Life and Counter-Strike.

Half-Life

I still don't know how people judge these things, I mean, story telling has never been good with FPS games no matter how many I played, that's right, not even half-life for me, and best multiplayer ones came from mods originally so they are not even franchises.(CS and TF being prime examples) We'll see if BF3 changes that though.

Half-Life (leader with 7th votes)

In the list... BioShock, Killzone and Halo (no specific order).

Half-Life.

Exactly this. I voted for Doom, anyhow.
