Best FPS game

here is a small list,

farcry
bioshock
painkiller
painkiller overdose
serious sam series
crysis
call of duty series
medal of honour series
turok series
half life series
stalker series
doom 3
counter strike
quake series
battlefield series
unreal torunament series
halo seires


mean while the games like hitman series, oblivion 4 can also be considered as first person shooters but they are not full fledged fps games.

Play these, you will take more than 6 or 7 months to complete these games..

thanks man i am really looking for such game
