Hello, I have a few purchase questions, I did not find any FAQ. 1) When I buy the download version, how large is the download? I have an ADSL line with data transfer month limit. 2) If I buy and download the game, will it be possible for me to install the game on a different computer than the one I downloaded on? I of course understand that the license will probably prohibit me from installing on multiple computers, but I want to download at a more convenient location and play somewhere else.
