As the first Pixar game to be produced in-house by Disney this game gives me optimism on the future of these games (at least for the next few movies) because this game was actually fun when it wasn't immensely stressful.

Based on the billion dollar 2010 blockbuster I saw in theatres when I was 9, the video game adaptation of Toy Story 3 is only partially an adaptation, with the bulk of it being a sandbox town in which you do quests for characters, build buildings and collect prize capsules.

The movie adaptation section is I believe roughly the same length, and vibe, as the entire Up game and would probably net this game a 3.5 score if that's what it was.
Eight levels in total feature either extended or shortened scenes from the movie, with collectables scattered around that help you in the Toy Box mode.
It's a pretty unremarkable movie tiein game but it's quite fun. The only problems I had with it were the things you had to do to get the 100% - trying to complete the stealth segment without getting caught was unnecessarily difficult and it almost made me give up.

The real meat is the Toybox Mode, where you complete quests for a Mayor Hamm and other toys from the series.
The more you play and buy, the more you unlock.
It is incredibly fun to just do these quests and even grind for the Gold Stars, which are essentially just miscellaneous tasks (examples: throw dynamite at townsfolk, do flips in a toy stunt car, etc).
The only things stopping me from rating this any higher are three things: controls, collectables and stunt cars.

The controls are...fine.
My main issue is for the Pict-O-Matic missions, missions in which you collect a "disc" of image stills of your town residents and you're tasked with dressing them up how they look in the picture.
To dress up your residents you pick them up with the Square button and throw them into certain buildings.
To redecorate these buildings you just hit Square in front of them.
If you dress up a resident and you need to take it to a certain building for the mission you'll end up accidentally trying to decorate it, and since your residents have AI they'll wander off on you while you try to get out of the menu.

The collectable prize capsules that are scattered throughout the Toybox area are annoyingly small and there's no real way to know which ones you do and don't have, short of cross-referencing three different menus. There's also no way to know how many you're missing, so at a certain point you'll grab one hoping it's the last one and being annoyed when you find out it's not, because now you have to find more.

This last issue is only minor since I actually got quite a bit of help with this one online but the stunt car section I feel didn't need to be there at all.
Sure, once you get the hang of it, it's rather fun, but the games already stacked enough...
