You Can't I'm Sorry :(
No, once a game is added to an account, it is non-transferable. The only way to transfer the game at that point would be to give the whole account.
yes if you have steam account and you have purchased games with it. You can log back into that account if you reinstalled your computer or what not and log into steam again with that account and have all those games still in there just have to redownload them :(
Yes it will only if there is a code that comes with the game that you can enter into Valve's database.
nope :(
You can't share a game between two accounts on steam, you'd have to buy the game again on the other account.
Yes. You just need to know their user and password then log in and you can install the games. Do note that this is a violation of the user agreements and could result in penalties and even criminal charges. You are essentially depriving the company of revenue.
A Steam ID is your online network game name. to activate steam go to steam.com and download steam, and create an account. And, steam is a gaming thing where you download games and demos.
If you have a Game Center account, just transfer that Game Center account into your new device . If you have another device without Game Center , just go on the computer and use a flash drive to transfer everything.
No, because you are not using Steam to play the game, you are only using Steam to verify the game and to use the multiplayer parts of it. If you have a Mac version DVD/CD of the same game then you could still use it on steam if you register it on Steam.I THINK if you bought the Windows game on steam they will let you download the Mac version on the same machine. They have the full instructions on their web site.
The game is not sold in stores. It is sold on a game selling company called steam. You would need to make a account on steam and buy it there.
You don't need to buy Skyrim from Steam, but it does need to be linked to your Steam account (by registering the serial code you should have got with the game).
It doesn't matter, if you have the game you can download it from your account.
