Good point - I was just about to hop on to say that I'm starting to doubt my prediction of an egyptian theme now (although don't get me wrong, I still think there's unlimited amounts of potential with such a concept and could be SO good if done right), mainly because the ride is obviously predominantly over the lake... doesn't quite fit the narrative of going for a desert theme does it.
Out of a mountain theme or an ancient Egyptian theme, I would choose the Egyptian theme any day of the week - but the more I sit and think about it, I'm leaning more towards it being the former rather than the latter.
Don't get me wrong, a mountain theme could also be pretty immense, but can't help but feel like you're fairly limited by what you can do theming wise with such a theme versus ancient Egypt... you've got hieroglyphics, mummies, etc which would all make for incredible theming. Whereas mountains? You've got the height and that's pretty much it.
I know the station doesn't look like it'll host a preshow, but I'd really like there to be one. I'd love for Exodus to be a complete encapsulating experience from the queue, ride duration all the way back into the station. At the very least, on board audio would be amazing (and something Thorpe haven't done yet!)
