Adult Fixie-skidders of LEGO

The prospect is daunting.

It is, but also immensely satisfying. We have a vague system of Ikea boxes for our Lego:

1. Small interesting bits (anything less than 4 studs long or 2x2 like
   lights, antenna, hinges, small Technic bits, etc) - This box is excellent for building micro-scale spaceships :)
   
2. Medium interesting bits (windows, turntables, wheel arches, etc)
   
3. Large interesting bits (canopies, chassis, etc)
   
4. Wheels (and axles)
   
5. Round things
   
6. Angled things
   
7. Blocks
   
8. Flat plates
   
9. Minifigs + accessories
   
   

It sort of works.

Now that this lot is mixed in with our original, more basic, blocks it is really hard to find bits to just build castles and towers with.

The advantage of allowing small hands to rifle through a large unsorted pile of Lego is that their plastic minds don't have fixed ideas of what a funny shaped brick is supposed to be for, so it can be anything.

Yes, you need to sort. However, the kids will jumble it all back in together in no time unless you take the 'new' stuff away, which might cause other problems.

Star Wars isn't actually even the worst for that balkanisation of parts. Things like Ninjago or that horrible new series Monkie Kid are worse.

In most new-ish LEGO series, they use about six or seven simple strategies to reduce the value (for a casual user, not for headbangers who build hugely complex things and sell stuff they don't want via BrickLink) of what you buy without making it too apparent.
