Quoted from hooch333:
nobody really believes in any of that wack-a-doo baloney, but they sure love to play the pinball machines!
The problem is not what people don't believe in, but rather what they do believe in. But I've already talked about that above.
If you are ignoring NT, I think that the part of the Red Sea is the top playfield action. I would also add a "destructible" Tower of Babel, ala Medieval Madness, because it would be flashy and easily recognized.
Might steer clear of the baby killing bits of the Moses story, which would throw out the plagues(unless you just ignore the last one). I'm fairly certain that bit would be overly controversial. You could do some desert wandering bits, kinda like the raft advance of White Water. Could be some good humor to be had from a Eden sequence. Have a mode where you throw apples at the snake, for example. A rain warning hurry up for a Noah's Ark sequence could be hilarious if done right.
