Not an RPG, but I'll tell you what game spiders do work in - Limbo.
If anyone has played it (which you should) you'll know what I am talking about. They nailed it's movements down to a pinch; it creeps and crawls just like a real spider lurking. Also the sound it makes is...disturbing - it purrs. Lastly, the amount of detail (though this goes for the entire game of Limbo) is fantastic; bare in mind this this is a black and white 2D sidescroller - you can see the little hairs on the spider's head, for example.
Captcha: mmunts monitoring.
Look busy!
