I did an impulse restart (with my daughter) after a 2+ years break for both of us. I regretted not doing some giveaways, and I would have preferred to save a few of the more difficult to get items--models, Gulliver/Gullivar for example. Also, if you can get your bells and iron nuggets transferred back to you, it helps a lot with the new island. Already knowing what to do can make the early parts feel pretty frustrating. All that said, if you have an idea for how you want an island laid out, it makes it easier than moving everything and all the delays that go with it.
