I think lego is awesome. But I'm too scared to let DS play with it because there are far too many little tiny pieces. We have got him some for Christmas/5th birthday coming up and so has my mum. I also got a box of second hand bits & pieces that I've put up for him. I'm a bit concerned about DD being around when he plays with it too as I can just imagine her wanting to eat it lol. I love the Lego friends sets they look so cool. I wish we had them when I was little. I loved playing with my brother's lego. It was the one thing we actually played together with as he was 6 years older than me and not interested in baby girls toys (can't imagine why lol). I've got DS a super heroes set. Mum got him a lego city helicopter & boat set. ETA: at the prep orientation DS found a box of lego in a classroom and played happily for ages with two other boys.
