I know what you mean, I was sceptical about it at first, then when I played it, I really enjoyed it.
What you do is basically go to houses, and you have missions, but to solve these missions, you have to use ghosts, like to scare people out the house, but it is more complicated, as you have to free other ghosts, and do stuff like, lure people to somewhere where there is a dead body or something... It get's really hard.
There are loads of places to go aswell, like the Clamitiville Horror, House of the Dead
