In all honesty, probably. I started Origin at it's birth so I'm no stranger to starting from scratch, however, I must admit that once I grabbed the properties I wanted to place, I quit playing Origin until shard transfers opened so I could get all my pretty pixels moved over. Granted I was also involved in the alpha test of ML at the time and was occupied with that, so that had some influence on me not playing Origin during that time, but part of it was wanting all my stuff moved as well.
The honest primary reason I still play UO after 12+ years is that I have yet to find anything else I like playing. UO is familiar and anytime I feel like playing I already have built characters and all the stuff I want to just go have fun. If that changed and my stuff was gone, I think I would be as well.
