are the socom games worth buying for (single play-story mode only) - NOT ONLINE?

and if it is, wich would you say is the best with gameplay, & things to do? also one that you wont get bored with after beating it once like black for the ps2.

& is it worth buying ((((((JUST))))) for single play?

also for single play in the ps2, will it include headsets so i can talk to the soldiers in the game?
