I have three computers that I use for different reasons. Two are portable, and one is my normal gaming desktop. Right now I have Steam (and related games) installed on my desktop, but I'd like to play some of the games on my other computers from time to time. Is it possible / legal / etc. (without getting my account banned) to install Steam and some games on the other computers? I have no plans to try to use Steam from more than one computer at the same time. On the other hand, what would happen if I forgot to shut Steam down on my desktop, and connected to it with my laptop? Would I get a notice saying Steam is already logged in, or could they ban my account for just doing that? Thanks.
