Japanese devs should do what Japanese civilisation does best - minimalism. They should give up the arms race for trying to make the most visually arresting cinematic experience possible, and just focus on making straightforward games. That's one of the reasons I think Nintendo has managed to remain so successful over the years, and is clearly the reason From has received so much credit for the Souls series. Do this, and I think Japanese devs will generate tremendous good will in both the hardcore and casual communities. There's a reason Nintendo was able to sell 81 million copies of Wii Sports and 34 million copies of Mario Kart Wii.
