Playing Devils Advocate here; isn't there no real difference than buying a model without paint, glue or basing materials?
It's how GW and the other game manufacturers have us in their clutches.
Basic question is this:- Will the separate clips STOP you from buying the scenery? (For me, no)
Don't forget you should be able to make one box of clips be enough for all three boxes of scenery.
After all are you going to have the Sewers, Streets and Buildings set up for every gaming session?
Fair points.
I was getting the impression that there were NO clips in the box at all. If there is enough to make a few buildings, then I understand a bit better.
So which is it? NO clips, or enough to build a few things.
