I've been through a couple lawsuits. It's almost not worth it. Your best bet here is to go after the government. A casino will tie you up in court for years without any settlement offers. They don;t care what the public knows.
The government on the other hand will offer a settlement once you make it past all the motions to dismiss your complaint. By settling out of court, they can hind all the facts from the public and get no bad press or flack from the general public.
