Try to level the volume between the music which is loud and the hosts which are not loud enough

Zoom out a little bit when filming the host so he doesnt have parts of his body offscreen

Add some better lightning on the host, it's dark sometimes

Better sync between the host and the questions asked on screen. There was way too much lag during the Matrix Quiz

Have the possibility for players to change their answers until the last second

For Quiz with no host, maybe add 2 or 3 seconds to answer, as sometimes it's tough to read some of the longer questions, the 4 answers and then have only 1 or 2 seconds left to choose the correct answer.
