Is this game worth it.

I am looking to buy a new game. I am considering ultima online to be one of those i want to get. Mainly when i get my new computer. Now im wondering, is this game really worth the money it costs to get it? What is it about? WHat is the purpose? What do you do in it? It seems fun from the brief posts that the members of this shard have said. Hey if its any good and you convince me, ill try to join your shard
