Electronics Arts or any other game company won't port games for Linux
unless there is a real commercial demand. Look up the cost for producing
a modern 3d shooter. It goes up to over 20 million dollars and has
something like a TB of content. This is unlikely to happen without a
huge desktop share leading to a proportional customer demand or some
vendor paying these companies outright to get a good port running.
Sorry, there are no easy answers, here.
