Modders should work on serious mods , look at all these Anime stuff , REALLY !?
And the worse part that they are popular !!
But...they don't HAVE to work on anything. Very few modders are die hard "future developers" and even actual developers. The rest are just average gamers that are playing around with the CK and other software to do small and kooky things like this.
But none are forced do any of it at all, nor are they getting paid for it. Although there is a donation option.
EDIT : Besides there are thousands of great and even truly EPIC mods that hold a close standard to professional woks of art. I don't care for anime either, but they are free to do what they want. The Nexus is just a way to share those creations with others.
EDIT 2 : Don't look at this as a mod. Look at it as a funny parody video.
Some people find humor in everything. Others find humor in nothing.
