IANAL.

Here's a random example from the Skyrim EULA:

   [You may] use one copy of the Software for your personal, non-commercial use on a single home or portable console or computer.
   ...
   [You agree not to] use or install the Software (or permit others to do same) on a network, for on-line use
   ...
   Installation on a network server is strictly prohibited, and this Agreement shall not serve as a network license in any manner.
