I find most Masterpieces to be poor play pieces actually. Megatron is the worst (his transformation's so tricky it makes Rodimus look like a Jumpstarter!). I find Optimus Prime/Convoy & Grimlock to be the most playable, although Grimmie ain't cheap. But yeah, on the whole Masterpiece are like really expensive articulated and transformable display pieces rather than play toys. But honestly, I get my Neo-G1 toyplay fix from Classicsverse than MP.
