Repetitive game is repetitive.
Unlike Lego Island the first one which was light hearted and more free roam and free play style and nice looking, this one is extremely linear. Basically there's mini-games at every turn, and alot of them are not that special and get old after playing alot of them in the first area or two. Some are hard, like the fishing one. But I don't remember the Johnny Thunder one.
While to a point you can free roam, the only things you will actually do at that time is run around on foot or in a vehicle either delivering something to NPCs, collecting things so you can move onto the next mini-game, or having to run around and talk to many different NPCs tediously.
Lego Island was easy going and fun and light hearted. Lego Island Extreme Stunts was a free roam game, action-adventure game, mini-games packed game, and skateboarding game all in one in a lego style all done well.
But Lego Island 2, you ask? Just read what I typed above.
