Worth Getting?

[Xylen]

Basically, I have had this game before but got rid of it because I didn't have Xbox live, it wasn't all that good mainly because I couldn't create my own character and the Mag system was gone you had that stupid robot instead, but I've heard alot of people are going online with it.

I want to know, what features in PSO are in PSU?
Is it worth getting?
What features are on the online mode?
Is it better or worse then PSO online mode?

Any extra information would be usefull to know, because I just want to go online with PSO but as we all know the servers have been took off and have been in that state for a long time, and there is no chance of PSO ever coming back online again. Not that I know of anyway.
