I downloaded this last night.
I really don't have anything positive to say about it. The download finally finished (slow as my mom writing me checks) at 12:45 am. I loaded it up and spent the first 15 minutes in the game trying to figure out WTF was different from the KR client. I honestly couldn't find anything different. I was horribly disappointed. The one difference I COULD see, is that the tiles looked WORSE than in the KR client. At least my boat didn't look like wooden tiles in KR, it sure does in SA. My poor bear rug in my house looked like a puzzle that was assembled by a 3 year old child. Terribad we used to say in WoW.
I can only hope there is new content, because as with most of the hardcore UO community, I'll be sticking with the 2d client. I know this is a rhetorical question, but who is going to play in a client we can't script in??
