There are two parts to film-making: the craft and the content. There are also two parts to video games: the craft and the content. Foreign content is always weird, but there is something else going on. American movies are the standard worldwide. In the US, we only watch American movies. In China they like both Chinese made films and American made films, but in the US we only like American made films. This is actually how it is in most countries. Most countries like both their own films and American made films, but in the US we only like American made films.
This relationship is very similar to the relationship between Japan and video games. In Japan they only like Japanese made video games, but Western culture likes both Western games and Japanese games. The Japanese like only Japanese games for the same reason that Americans only like American movies. It's because for both media there are two components the craft (craftsmanship) and the content.
Every culture tends to prefer content from its own culture. When it comes to craft...well I'll let you figure out which culture is best when it comes to craft. I'll just say one more thing: I would be very shocked if Germans liked playing board games that were made in the US.
