any good fps that has these features like,
-customizable weapons(like barrels,grip,Magazine)
-long story line or alot of missions
-nothing scifi more like army or swat
just trying to look for a game i can test my mouse out on
personally i like call of duty (first one) just cuz its set on WW2...i really havnt played most of them but here is the deal:
If you want to play just for the story go for the Call of Duty
if you want for customizable weps go for Call of Duty 4 (i cant really remember if you can cuztomize your weps on single player but if you go online, you battle for rank and the higher your rank the more weps you get and more customization you can do..)
I hope im not too late,
S.T.A.L.K.E.R. clear sky is pretty good, and does all of the things you asked for.
It is however quite buggy at the moment (awaiting patches.)
Essentially it is the Ukrainian call of duty 4. Thats what it is. I also suggest you buy it's predecessor Stalker shadow of chernobyl, there is alot of atmosphere to these games, the odd bit that might make you mess in your pants, and some bits that will make you attack your compooter, but over all good solid fun...
