I'm dying for an MMO to tide me over until some of the other sandboxes and semi sandboxes(A little wiggle room for me, to keep the die-hard sandbox definers at bay).  I was looking at UO when I saw they had a 'newer' one dated 2007 with an enhanced client sometime after that.

The question on the table is whether or not it's worth investing some time in, or better to let sleeping dogs sleep.
