It is sad to admit that I have enjoyed playing this. I have played it with my 3 year old, who loved the split screen in toy box mode and basically we just played hide and seek!
Also played it with my seven year old nephew, who absolutely adored it (despite being more into Ben-10, Pokemon etc).
The sad part is that once they stopped playing, I was compelled to continue!
I have only really played tox box mode, so won't comment on Story Mode, other than to say I think it is up to the same high standard of graphics and cut scenes that are in TB mode.
TB mode is a good mix of free roam and missions, which are maybe a little easy for an adult, but no less fun. Having said that there are some really clever bits in here, the 'Goo' that you can throw around turns things bigger or smaller and must be used for some missions and the sheer volume of missions compensates for the relative ease of some of them. Both main characters (Bo Peep, Slinky, Pork Chop etc) and non characters ask you to do missions with more areas and interactive toys being unlocked as you go.
The only gripe I might have is game length, I suspect my nephew and I raced through over 50% of TB mode in 5 or 6 hours. But is soo much fun, I am sure there will be bits we missed and we haven't even looked at Story mode yet! I also suspect that if Disney/Pixar have any sense, they will release DLC, as this is a collect toys kind of game.
Good to see that some-one has sat down and thought out a game that not only coincides with the film (which is also great) but stands up in its own right.
