As you probably already know wi-fi is a common term used to refer to wireless internet, so the answer is no, you shouldn't need wi-fi for game add-ons. And any standard internet connection should be suitable enough. For game add-ons you should either be able to buy them on disc from a store or download them via the official site.
only for some games. i think you need wifi to set it up, i may be wrong. to download a game from the eshop you need wifi, but to put in a physical copy of a game and play it dosen't require wifi unless the game requires wifi.
No you do not need wifi to use the gameboy emulator.
because you need better wifi
Yes, to add addons to the addon list in Blockland, you typically need to extract files from the downloaded addon ZIP or RAR archive. Once extracted, you should place the files in the appropriate "Add-Ons" folder within the Blockland directory. After that, the addons should appear in the game's addon list when you start Blockland. Make sure to restart the game if the addons don't show up immediately.
You do not make any sense!
You will need a game that has wifi campability.
Any addon is legal as long as it follows blizzards guidelines. Hence, most addons are legal.
You have to find an addon first that is supported by cataclysm. Then once you have one you put it in the "Interface" folder in the world of warcraft folder. There will be a folder in Interface called "addons" thats where you put the addons. then before selecting your character when you are almost in game you need to click on manage addons in the bottom left corner and make sure they will be on. one good place to check out for addons is the curse addon site listed below.
Choose the WiFi option on the main menu of the game. You need WiFi or some sort of Internet connection.
You need to access the internet from your PS3 to go to the PlayStation network from your PS3. It does not have to be WiFi it can also be ethernet cable, but nothing else
Well first you need a router which allows you to play online and such. (There should be a wifi area in the game if that's what your asking.)
You do not NEED Wi-Fi for any part of the game. You can enjoy the game best with Wi-Fi, but you do not need it.
