4yo recently taken a shine to our 20 year old lego set, which doesn't consist of much having been shared between 5 cousins and now him.
are there any good "all round" sets?
ours came in a bucket with lots of normal bricks, a few animal ones, wheels, doors etc.
so you could build anything from houses to vehicles to creatures with it.
all the non-specific sets appear to be duplo.
