I know, I'm just trying to illustrate that 'relative prices' is a load of bollocks. GW models are cheaper per model, but they are wargames, not skirmishes. So you need more. But you need more for historical wargaming too and I don't see PP players hanging out on Napoleonic wargaming boards telling people to stop being corporate tools and buy PP.
A proper comparison would be Necromunda, both skirmishes. Using the PP starter set, 5.8usd per model, using GWs gang kits, 4usd per model. Rules are free on the GW website.
