I couldn't agree more, I would like to see more different figures in themes like there used to be.
It's the figures that I like the most in the themes that I collect and when Playmobil brought out the new look Knights in 1993 the sets that followed gave us over 100 different figures and only a couple of sets had figures repeated in them (3887 assault tower and 3888 castle defense).
Unlike today all of the newer Knights, Viking and Barbarian sets are made up of just a handfull of figures, the 5 Barbarian sets have 15 figures in total between them but there are actually only 8 different figures.
I guess it's down to cost 8 molds is a lot cheaper to buy than 15, at least we get the specials every year and this year has been a good one for me.
