All in all, the biggest issue with Showdown is the guns and the scoring system. They're just not reliable. The speakers in the cars aren't as good as they were too, the "You got a Bonus!" Sounds like it's being played by some cheap low quality speaker. Another thing i noticed, when riding with a friend or family is that if you get a bonus point, the screen shows it, but the person who also shares the screen can't see their score when the bonus audio is being played.
Personally, I think it's time they scrap the current score system as it seems really unreliable, filled with obvious flaws (the screens), not as advanced as the Golden Nuggets one, which could record high scores of the week, month, and entire season AND display it. It had a more robust seven segmented display (the screens are really distracting personally), with better speakers for "You got a Bonus!" While other riders can still see their score.
On the guns, it seems like you don't even have to aim, just point it at a certain area and you'll almost without a doubt hit 2 targets, then they'll immediately reset, again, you'll get more points. A bit of a challenge would be nice with targets that done reset instantaneously.
I wonder who made the Golden Nuggets scoring system. I'd love to see a modernised version of that back in the ride!
