@Miraku Red is nice because it appears in a lot of character building systems. Throwbots, roboriders, bionicle, galidor, knights' kingdom II, ben 10, hero factory, minifigure subsystem, homemaker figure subsystem, technic figure subsystem, big fig subsystem, all different shapes and scales you can play with.
@Cocoa Yeah but the only strategy is to parts spam. I agree it that looks good but it doesn't require any practice or skill to do it. I imagine the process of tediously stacking throwbot arms in sequence wasn't very fun despite being a competent use of resources. I'm guilty of doing the parts spam too and I don't enjoy it. Finding new npu solutions is what I like doing. Parts spam is a necessary way to get texture though, I agree. Parts spam is to beats in music what npu is to a guitar solo.
