We've loved Lego too (still have heaps of it in the loft, ready for grandchildren, next to all the Playmobil, I can't wait to get it all out again he he). However, I don't like the fact Lego cash in on the gender-stereotypical, eg, pink buckets of bricks aimed specifically for girls, and as someone said above, angry-faced baddies. They also cash in on films, like Star Wars and Harry Potter, for instance. Playmobil doesn't do that. Yes, they have the mansions and dolls houses, forts, pirates and castles, but it is not specifically aimed at either gender, and they don't bring out film or well-known character-based ranges. Daughter, son and all their friends were all happy playing with the pirates, cowboys, knights and doll's house, and they all played together happily. The End!! 
The mansion was particularly bad at falling to bits though - the number of times I had to rebuild that thing - Grrr. The first time was Christmas Eve, when o/h and I had planned ahead and put it together so we wouldn't have to do it on Christmas morning. Carefully getting it out of the loft (just outside daughter's bedroom it fell to pieces, with all the little bits clattering down the metal ladder. Aaarrrgh. Thankfully, it didn't wake her, but of course we had to build it again, and by this time we'd both had a glass or two of wine hic
JohnnyBarthes - Playmobil do have the 1-2-3 range, which is much chunkier for little hands, with none of the tiny bits.
