Infantilized Aesthetics

[InkstainedGwyn]

I'll buffer my point with the added fact that this is happening across game genre's.

MMOs are far more accessible these days than they used to be. Players who were once high-school/college age "rebels" playing these MMOs are now adults with jobs of their own. Games have become much more of an acceptable medium of entertainment than they once were, and because they're more popular, they're becoming far less niche than they were, which means the aspects and details that they take on are going to become more "commercial".

That's my take on it, anyway.
