Whilst re-playability is certainly there as there is a whole heap of hidden stuff to find, and a lot of it can't be found until you unlock the Free Play modes for each level, it's hard not to get the impression that the LEGO game series is starting to run out of steam. Word has it that Traveller's Tales has acquired the licences to other movie franchises like Harry Potter and The Lord of the Rings.
MyGEN would like to think that if they do have these two additional properties, they may give the franchise a bit of a breather, think up some really cool new features (some minor RPG elements anyone??) and then give the series another bash. That being said though, these games are great fun to just pick up, play a few levels, and then come back to it in a few days time.
