Single player is one of the best first person shooters out ever. Multi-player is very addictive with great graphics.
I recommend this game to anyone that likes playing tactical games and having a great communication to win is the main key to winning at this game.
Socom 4 is also newb friendly for the newcomers appeal, I'm not a respawn fan but I have found myself playing the standard mode quite frequently, I guess it's easier to rankup your gun mods this way.
The Socom feeling is definitely there in the classic mode, intense camping and struggle to stay alive is my favorite, I just hope there will be more game modes implemented through patches.
