So I've been on a bit of a spree since the cancelation:
Anakin Skywalker - Solid looking figure although I don't care for the pose at all. My favorite SW character so I'm pleased with it even if I can't stand his clone wars voice.
Obi-Wan - Much more fitting pose than Anakin's, translates much better to the cartoony style too.
Darth Maul - looks fine, although it is one of the sloppier figures I have.
Luke Skywalker - fairly plan and doesn't capture Luke all that well.
Leia Organa - One of my favorites, the pose and expression are fantastic.
Han Solo - I was hoping the figure would look better than the render but it still looks more like adam driver than it does Ford.
Chewbacca - I hated his render so I wasn't really excited to get him but man he actually looks great. Great size and he doesn't look so aggressively cartoony like I expected
Darth Vader - Looks good, bigger than I expected.
Sabine Wren - I don't know anything about her since I don't watch the show but I love her infinity design. The figure doesn't quite measure up to her render though due to the face being kind of iffy.
Star Lord - looks pretty good all around.
Gamorra - very nice although her sword is a little bent.
Black Widow - looks really poor up close
Iron Man - fine
Thor - fine
Aladdin - Like the pose and expression, really captures the character
Stitch - Very nice although I wish I had a Lilo to go with him
Alice - Say what you will about the movie but her figure is marvelous.
I have Ant-Man, Vision, Donald Duck, and Captain America on the way from Gamestop
I already had the Incredibles and Mulan who I'm very pleased with.
As far as playsets go I have: Twilight of the Republic, Rise against the Empire, Guardians of the Galaxy, Avengers, and the Disney Infinity 1.0 starter trio.
Is Battlegrounds worth it? The 4 player mode sounds like fun.
The rest of my purchase list:
Hawkeye
Hulk
Loki
Falcon
Spider-Man
Iron Fist
Drax the Destroyer
Groot
Rocket Raccoon
Black Panther
Yoda
Boba Fett
Mickey Mouse
Princess Jasmine
Tinker Bell
Jessie
Jack Skellington
Quorra
I have to say I'm sorry to see the line go. I was pretty apathetic to the initial wave but the figures really improved over time. They really needed to a better job of picking characters though. So much of that first wave was a waste and there are so many classic characters that never got represented.
I haven't really played with any of the figures yet but I have Disney Infinity 1.0 and 3.0 so I plan to in the next couple days.
