After last year was somewhat shallow Disney Infinity 3.0 is a little bigger on Gamescom this year, with several tabels to try both the toybox and the Star Wars levels. Could take some pictures (as nobody stopped me) of the new skill tree which seems to divide in four sections. However nobody could tell me if there's more than level 20 to achieve (all character are on level 20).
Unfortunately, Olaf isn't playable, though he's on one of the plattforms. But Mickey, Minnie and some Inside Out characters are.
Health (Thor)
Rocket Fire (BobaFett) (seems to be the special ability/attack of each character)
Damage (BobaFett)
Range Attacks (BobaFett)
Then there is a more detailed overview of the character abilities (like is his ability jump, strength, flying etc)
and pictures of the disney characters
and Olaf
