Most definitely. No aspect of the game requires internet connection for playing. All that is needed is a working copy of the game.
Yes you only need WiFi to play online
no, the internet is only needed for full use of all the PS3 features and Games can be played without going online
Yes, but you would only be able to play it singleplayer and I believe that you would need to be offline(without internet) Same goes for regular Minecraft Client.
Yes you can use the controller
First off the G.E.C.K. can only be used on The PC and you will need the fallout 3 game installed to use it combine the G.E.C.K. and softwares like blender or 3d max to create good mods and what not the geck is a item in fallout that can only be used on a quest
Yes.
Yes, it is possible to play Microsoft Flight Simulator X without an internet connection. The only things you can't do without an internet connection is use real life weather and play multiplayer.
Gladly,no.You can use the keys to do it but I'm without doubt that there is a possibility of a controller.Like me,I play fallout 3 on my PC and I use keys.Kinda hard but you just got to get used to it.
Joystick for Fallout 3?No, Fallout 3 is set up for use with keyboard and mouse on a PC.or you can have it on a console without a keyboard which is better known as a controller
You don't. It does not exist in fallout 3 without the use of the console and mods. ( Only for P.C )
Yes you only need WiFi to play online
A PC is not involved in the use of the PS3. I don't even know how you would use the PC with a PS3. I have both and they are both connected to the internet. If you are asking how do you use a PS3 without internet and using the word PC for the internet it does not require the internet to use the PS3 it just gives the PS3 the ability to do more and to make sure the PS3 and the games have updates. Of course without the internet you can only play offline
Sleep
After the download I do not think so, once lauched once and a new profile created you can play without an internet connection.
No you don't have to have internet to use any Call of Duty games. The internet is only needed if you want to play online, for example on xbox live, wii network or the playstation network. You can play the campaign missions without the internet.
no, the internet is only needed for full use of all the PS3 features and Games can be played without going online
When you download the game after buying it, you have to sign in in order to play on multiplayer servers. However, you can still play the game without signing in to a valid account and play single player.
