My son and I did all 3 sets. We like the 3-in-1 sets best because we're really motivated to take them apart and make them new - we just don't do that with other sets. My son is almost 4 years old and said this is his favorite game (we have mythical creatures and dinosaurs which are super cool) - I think the light and the fact that it's a robot with lots of moving parts helps. He played with built-in robot models as toys - they hold up well. While I've always been fascinated by Lego using the same pieces in different ways, my son actually noticed the creativity in using light for eyes, a laser. , and jet afterburners - that got him thinking - which is priceless, isn't it? The instructions are simple enough that he can follow them with a little help (although he was a lot easier with the dinosaur set at his age). As we both love to build, this was the perfect opportunity to work together. , practice teamwork and have many small learning moments. :-) My only complaint (if you can call it that) is that other kits have a "secret" 4th model if you go online - so far there are only 3 in this one.
