a few questions

ok so my first questing is will 3.0 come with all the stuff from 1.0 and 2.0 if u have the clear thing to unlock it? also i am buying it again for a different system so will my charters have to be reset? and was there any kindof of cloud storage? or will i have to start all over?

You will have to start all over. Each console is separate and nothing transfers over to a new console. Your character levels and skills will remain if you select share ownership when you first put them on the base, although there are occasional errors that might require you to reset a few characters. But leveling up again is really not a big deal. If you have the 1.0 and 2.0 playset pieces, then putting them on the base will unlock the associated toys. But even if you don’t have the playset pieces, you can still purchase the toys using sparks. The Disney servers were shut down so there is no way to download toyboxes that you may have saved on a different console.
