WWE 2K22

Slightly different set up to the other listed. I personally found this way easier:

Go to Options -> Gameplay -> Balancing

Ensure that the following are taken all the way down to 0/100:
A.I. Standing Strike Reversal Rate
A.I. Standing Grapple Reversal Rate
A.I. Ground Strike Reversal Rate
A.I. Ground Grapple Reversal Rate
A.I. Finisher Reversal Rate
Stun Gain
Stun Duration

By choosing these options as soon as you deliver a few combo punches to the AI, they'll enter the stunned phase, making them easier to throw out.

Secondly: Go to the Royal Rumble in the Play menu. I chose Brock Lesnar, then Match Options. Then edit the participants in the match. Select everybody in the 70 ratings and as low 80's as possible. Set the Entrance Interval to 180.

By choosing the interval to be 180, you'll only ever have to deal with one person in the ring at a time. A few combos / Brock's F-5 and you'll have an easy elimination. Once superstars are eliminated the countdown will automatically start from 10 for the next person to enter.

I did this first try by using the above settings and never had more than a 1 vs. 1 in the ring at any one time.
