Anyone who is a fanboy of Final Fantasy 7 and every Final Fantasy game/movie after that is not a real videogamer to begin with.

Plural 'fanboys.'
A male variety of fangirl. These are males of any age though usually teens that are obsessed with anime and will often turn rabid over getting the latest copy of their preferred manga. Unlike a fangirl, fanboys tend to be a little calmer but will still start an online or real life war with you if you say anything bad about the anime/manga they like.
A fanboy will either streotypically be into mostly female characters with big boobs or strong personal or mostly epic male characters which they cosplay.
Some fanboys are however tame and enjoy detailed conversations about the thing they are a fanboy of and are open to suggestions of other things they might enjoy (unlike those who are so stubborn they think anything they haven't heard of must be rubbish)
They can be see with badges/stickers/keychains of characters, reading or drawing manga or playing computer games on hand-held devices.
Fanboys can be a fan of yaoi or yuri but will be unlikely to admit being into yaoi.
Not to be confused with an otaku or a weeaboo as fanboys don't have to be obsessed with something Japanese but dominantly are to a respectful if scary level.
