Some are pretty good and fairly easy to play with no knowledge of Japanese, vol 32: Zombie Crisis is like Touch the Dead, Vol. 42: The Haioku Byoutou is a kind of point click J Horror, I really like this one and the other one I tried Vol. 21: The Fuhyou is like Brothers in Arms.
They cover a real range of games but I these are the ones I've been able to follow.
