Will play sets have replay value?

Do you reckon there will be any replay value in the play sets? I wonder if you finish the missions that's it??

Pffft. With toy box mode, you could just create your own missions based on existing play sets.

But it would be nice if those play sets had some replayability.

I have had confirmation that there will be hidden collectables throughout the playsets. Instant replayability there.

I know they said that with the Pirates playset, certain areas or treasure will only be accessible to certain characters (like with Skylanders of a different element), so there's replay value in playing through it with the different Pirates characters.

This is great news. It just keep getting better.

That's a something I've worried about as well. I mean...six hours isn't a lot of gameplay for most video games, but the Toy Box allows for infinite gameplay, so there's that.
But since there's hidden items, and unlockables do to additional characters, I'm sure people will be entertained for a good long time.
