I assume it's a licensing thing for why they do chimes and why they rerecorded the voice callout.

It was a good episode of a good show (I won't get into how the video game part of this was different, but suffice to say...they didn't find a bunch of mint arcade machines that had sat in an arcade for twenty years)

Do another zombie game. Sure why not. TWD is excellent, but we can use another. It's been 10 years and it's the only other zombie game.

Season one/the first game is basically a road trip story. So have a map and progress across America, like Jurassic Park. Have stops in Boston, Pittsburgh, Kansas City, Wyoming, Colorado, Washington (season two will probably be in and around Seattle).

Without getting too spoilery for the game and what they'd do for season two, it is more of a revenge story and chasing someone around.

They could reuse the drop target concept from TWD as the game, and the show to a minor extent, is about scavenging for supplies/weapons.

Have an infected bash toy

you're trying to tell me gun silencers aren't magical devices that make a gunshot whisper quiet?

sure on actual film but with modern digital cameras, it's easy to set the capture rate to the same as the monitor. Even most modern cell phones let you do this.

Then in editing they can cut the frame rate back to a normal 30FPS

Maybe I'm mistaken, but most raster CRTs have a fixed refresh rate (they may offer more than one and you can select, but it isn't changing on the fly). The video game isn't necessarily at a fixed frame rate, but that isn't the CRT refresh rate

I believe vector CRTs use variable refresh rate, and now variable refresh rate LCDs are starting to become common in gaming
