In Juon: The Grudge it is VERY hard to find out what to do, where to go, and where to find batteries. The lighting in the game is a large issue. If you have and HD TV I would suggest you crank the brightness. With the gameplay, the controls were VERY unstable, the scary parts weren't that scare, but they had there moments, and the chapters were nearly endless. But, I honestly had fun playing through it with friends. So, if you want a cheap scare this is the game for you.
Ju-On the Grudge is a scary, fun, and tense experience, and it's definitely fun if you plan to play something alone at night for the sake of scaring only. However, I can't say much of anything for its quality as a game. The control is bad, and the mechanics are bad. (The whole b to move thing may have been immersive, but I just kept ending up walking in circles, running out of battery and dying. Thumbstick please!?) In short, if you're looking for less of a game and something more akin to a 2-hour Wii motion controlled version of an internet horror flash (such as The House) then this is for you. If not, don't even think of it as an option.
