1.0 did a solid job with its playsets, as each one felt unique and different through extreme (driving mechanics in the Cars one) or through simple changes (different types of objects in the Lone Ranger, Toy Story and Monsters University Playsets). Each one had small issues but overall they were good uses of each IP
.
2.0 was playable but nothing special. Avengers and Spider-Man are completely inter-changeable; they might as well be the same playset. Same core hub areas, same types of missions and a focus on beating up mindless foes really put an damper on things. Guardians of the Galaxy is better but that is mainly due to the cast you are playing as, the world looking very different then Spider-Man/Avengers and the mission types being slightly different. Its a shame that it was so underwhelming but at least the Marvel Figures have a lot of moves to play with.
3.0 seems be a mixture of the best parts of 1.0 and 2.0. You have the expansive variety that 1.0 had with different types of games (3D/2.5D Platformer, Action/Adventure games, Diablo-style game, Kart Racing game) with the similar gameplay styled playsets being unique through very different locations, different focus on mission types and gameplay feeling different (Twilight has a focus on Lightsaber combat, pod racing and exploration/Republic has a focus on hub world mission completing and space battles).
The Toy Box Expansions (Takeover and Raceway) do a lot in making Infinity 3.0 a great package for everyone; you can use all your figures from the entire Infinity line (outside of the Cars ones for Takeover), they are just as long as the normal playsets and they feel very different then the playsets. Hope 4.0 takes this a step further with a greater focus on playsets that allow for characters to cross-over with one another.
Star Wars figures working with every Star Wars set is already as step there and the Toy Box Expansions show promise of that being fully fleshed out, so hope that 4.0 goes wild with this idea

Muppet's and Kingdom Hearts seem to be great IP's to focus on for future Infinity games, so lets see what happens
