If you are out of idea, maybe try to use a generator website like https://commentpicker.com/team-generator.php
Add a list of game genre names:
adventure
fps
card
fight
rogueLike
flight
racing
shooter
musical
city sim
p&click
survival
turn based
puzzle
interactive/choice story
battle royal
horror
stategy
...
Then use the `Generate teams by participants per teams` with 2 participants
And press `generate`, you will find funny combination 😀
Have a good jam!
