Ah the game... no? Never play it so I don't know what's that about so any comparasion to the game lore and such well I am not the person to talk. The movie itself is a good horror stuff. To be honest it's a bit weak in terms of horror and in terms of plot but had it was okay done. It is one of those movies you watch on a night and tomorrow is out of your mind. Serve the purpose.
We've got a guy who is haunted by the kidnapping of his brother and ends up being taking care of his sister. To not lose her he gets a job as a security guard in an abandoned place (why?). At night strange noises and strange things start to happen. A policewoman who visits more times the place than him helps him settle in and even helping on the place. Meanwhile his aunt wants the custody of the child (due to money) and puts some guy in that store to smack it and he be fired and that's where we meet the monsters/robots and such.
Everything is more or less connected and they try to connect all the dots of the kidnapping (still don't understand) and the toys. The story behind the toys is a bit of a stretch.
No Nudity.
