I started with 1.0 and launch and 2.0 at launch. I feel they all are worth it in their own way. Honestly if you got the cash get it all. However the 2.0 playsets are the weakest of the 14 playsets that have been released/announced. If you love Marvel then worth it for the expansion games. 2.0 is the only release with a tower defence expansion game.
If your interested in the toybox then don't bother going back a version.
But here the biggest incentive to own the previous playsets, in 3.0 it will unlock everything associates with the playset. This including the 4 expansion games. And hey more figures!
I would look for it new or complete because 2.0 comes with 2 expansion games and a full poster.
