There are times I'm playing on location and certain sound effects sound the same as on other games. Not really a reference but like a Pavlonian response that psychs me out. I think Jack Bot has some of The Shadow's sounds or vice versa?
LOTR jackpots are similar or the same as IJ if I'm not mistaken with John Rhys Davies calling them out. I only played IJ once or twice so someone else can confirm that.
