80s computer game's typeface size is best (5)
I believe the answer is:
elite
'is best' is the definition.
(elite can mean the very best of a group)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for elite that I've seen before include "Creme de la creme" , "A privileged class of people" , "Group enjoying superior status" , "First-class" , "Cream, the pick" .)
