This is a 1989 Atlantis table from Bally recreated from a program called Visual Pinball. Whereas Farsight studios (who owns Pinball Arcade) has to buy licenses from the manufacturers to legally be able to make money off of them Visual Pinball is freeware. It's open source. The upside is it's free. You just download all of the software and play. The downside is it's somewhat complicated to setup as it requires multiple programs and isn't as user friendly as Pinball Arcade which is essentially plug and play. Pinball Arcade has about 60 tables and licenses so far but Visual Pinball has 100s of tables you can play if are willing to set everything up. Pinball Arcade is the better product currently but Visual Pinball allows to you to play tables like Indiana Jones, Tron Legacy, and Back to the Future that Farsight might not ever be able to secure a license for due to high licensing costs.
