Only buy this if you have a plethora of free time and love Legos... AND if you are extremely creative.
For instance, you can order a guy to drive his car into a wall, shattering the blocks, and having a carefully placed exploding block nearby to set off a chain reaction of flying Legos in every direction, and you could even make flying vehicles and create "satellites" that sit up in the sky, dropping objects off. Like I said, you need to be creative with this game... ha ha ha...
There's one actual playing element, and that's controlling a character or flying a plane or blocks assembled with an antannae - which makes it flyable - and going all over the place.
This is about as open ended as a game can get, so have fun. If there were online mods available out there, this actually could be made VERY fun...
