I have a complete World of Warcraft battlechest I bought a few months back. I installed it and played for a day or two and got bored of it and haven't played again. I have since uninstalled it and it has been in the box since then. I was going to give it to a friend for Christmas, but was wondering since I isntalled it on my PC at one time will he be able to install it on his? I am not very familiar with PC games so I am not really sure. Thanks for any information!
