Or TFB, since Sheep Wreck Island and Tower of Time did the same as the SSA packs.
But in general,Magic Items just kinda seem to be the bottom of the barrel for both devs. I'd have loved if you could unlock at least maybe themed testing tracks for vehicles or something,since it'd be just a matter of porting assets from TT - but chances are even if it was in plans at some point, it'd never be high priority.
