I like building/displaying model kits, particularly Master Grade Gundam kits. Also car kits, spaceships, pop culture vehicles.. as a kid I'd pursue various action figures but nowadays I'm mostly interested in things you build. Like I'd rather find a Bayonetta model kit than an action figure, for example. There's always more kits I wanna get, like when I like a certain series I'd like a kit from it, though I haven't gotten anything in a while. Last Gundam kit mighta been MG Epyon.
It bugs me when the figures have more features than the kits though, like how the Eureka Seven figures have the transforming feature but not the model kits.
