3.0 is the most advanced Disney Infinity game and for that it has a lot to offer in terms of creating levels or exploring playsets. This one like 2.0 is bloated a lot with one franchise being Starwars in this case, but they also made a lot of regular disney alongside it and even made playsets for non Starwars franchises so it was less of a problem. While I favour the first Disney Infinity due to its charm, this is the one I go to if I want to be more serious with my level creating.
By far best game in the Disney Infinity series. Toy Box continues to be good, but they didn't leave Play Sets out in the dust this time. They also actually remembered their other franchises this time, unlike 2.0 which was all Marvel all the time. This one didn't neglect the Disney/Pixar/Marvel sectors despite the Star Wars focus, and while it was sad that the series went out after this, at least it went out at its best.
