Using content from a wide variety of asset packs is a problem because it means the resulting game will be visually and thematically incoherent. You can see a lot of this already in their demo videos -- there's visible conflicts between their realistic and cartoony content, detailed vs. lo-fi, shiny vs. gritty, fantasy vs. science fiction... this all makes for a real hodgepodge of content in the game, and it's going to be difficult for them to resolve in the future in a game that's meant to rely heavily on user-generated content.
