The main advantage of the "shard" system is that you can use the
same game world multiple times.  It reduces the development cost.
Usually, there still are multiple machines per shard.

Of course, if the landscape of your gameworld is algorithmically
generated, and there is little or no static "content" (players have
to create their own cities and so on), this does not apply.
