Less in my opinion. Thanks to hiding the amounts, both Noah and Bosman were able to make some great plays, maximizing their items, to get the kill while still picking the easiest question that would secure the kill.
It's the only element that isn't just a pure numbers game. I'd hate to see them get rid of it.
On the elegance, if they had the budget for it, it would probably make most sense to get a smaller monitor for each player that only they can see, which gives them a private feed. As I understand the game is built in Unity, which supports up to 8 screens from 8 cameras out of the box. However there's also the recording aspect as well. It would be a pain in the arse to record all the different camera shots, the main game screen, AND 3 additional screens.
I think the simplest solution would be some sort of fun prop. Each player could have a stick with a small panel on the end, like a fan, that they have to put in from of their face whenever another contestant is using analyse. They could call it "Mysterious Myst" clouding the eyes of the contestants, or something equally thematic.
In terms of gameplay, I think being able to analyse for free is too OP. Bring the upfront cost of the Analyse items down and then have the items reduce the cost, not negate it entirely.
I also think it might be fun if, at the end of Round 2, players had the opportunity to Sell any of their items (shop bought only, no Lucky Loot items) back to the Shop for a small amount of gold. I think it would add a fun amount of strategy going into the final round., especially if it's a close race up to that point.
