I've been wondering the past couple days; how do you guys decide what goes into your collection? I've decided to go all in on Titan's Return & realized this is the first time I ever wanted to get an entire line of toys. And with how deep the franchise is I know there has to be a myriad of ways fans setup their displays.

So what's your method: Series? Characters? Teams? Gimmicks? Classes? Designs? Favorites? Everything?
