Do these games require internet conection to activate the product key on PC. Please i need your help. Is there any fps,rpg,rts games that do not reqire net connection and the game should be recent ones. I don't want to play online. I just want to play single player. Please help me.

None of these need an internet connection to play.
You shouldn't have to activate any CD keys either but (I know you've said you don't want to) but if you want to play online, obviously you will need a connection.

you should be able to play all of these offline.usually you only need the cd key if your going to play online,so you shouldn't need to use yours.hope this helps.
