A = Great (81 to 99)
Great. Everyone should play or watch.
B = Good (61 to 80)
Good. Worth playing or watching, and if a retro game is still good today.
C = Average (41 to 60)
Average. Playable or watchable with good and bad points.
D = Bad (21 to 40)
Bad. Not worth your time.
E = Terrible (01 to 20)
Terrible. Avoid at all costs.
