You could not build a proper legion with Airgam sets.
The same way with playmobil, no? Of course, Airgam are not available in the hundreds (at least not easily), and so a "pop tub" to fix them would be harder, I suppose...
I am very fond of them (everyone knows that by now), and the quality of the figures is not so bad (except for the design flaw in the feet!).. But a lot of the accessories are really really lousy.
And of course, that happens with playmobil, and being larger, it's even worse with Airgam - the "big stuff" is tiny. The roman ship is small for playmobil... ridiculously small for Airgam (as documented).
