Johnny has used 3 different ways of giving his thoughts on games during reviews.
5-point rating system
This rating system contained numbers 1-5 with games rated 5 being the best and 1 being the worst.
10-point rating system
Johnny started using this rating system because it was more "versatile". Games with a 10 rating were now best while 5 was now the halfway point. The following games received perfect scores:
Johnny gave Superman 64 a -64 out of 10, his lowest rating ever.
No rating system
Johnny stopped using the rating system in 2012 with his review of Sonic the Hedgehog 4: Episode 2. Now he just gives his thoughts on the games and doesn't rate them.
