If PSU is run anything like EQOA, this is how it will go:

1. The only thing stored on your memory card is your personal acct info, ISP info, & other such necessary tidbits to access your chars online.

2. All chars are saved server-side (we already know this is true in PSU).

3. All patches, updates, etc. are also done & saved online. Info is accessed via the game disc & with write-ups for scenarios, the final info is added to & saved on the server. If its time-oriented, the material is removed when the admins deem so.

The smart way to go about this is to purchase a new memory card. This is true especially if you intend to have more than 1 char, plan to spend alot of time on this game, & youre probably already a PS2 game owner & could use more space regardless.
