Ok, dude. You don't have to play, it's cool.
Some of them rub me the wrong way (yes, only on xbox is so putrid and lazy, and luigi caps are starting to just signify dunce caps), but some of them strike me as just fun. I liked the Raiden glowing eye thing, I liked the Ni No Kuni nose piercing thing, etc. When these things arise naturally from people being excited or liking something, I think that's cool. I guess that's why I don't like some of the others, because they seem forced, and retaliatory.
So yeah, I'm a bit on the fence with this one, or have been, as it isn't a "hey, I really like this game!" or even the developer, but a huge platform holder, which is a little fanboy-ey for my tastes. However, in this instance I'm a big, BIG fan of the way the Kaz and Cerny meme of putting their faces on stupid fun gifs came to be. That was organic. And fun. Putting them on avatars seems to be a sensical next step.
And it's not about pimping anything, in this case either. I only got involved in trying to get an oddly-shaped mango to have a Cerny face on it, because I thought it would make me laugh. And it did!
