GTA is a thing. But not by name, really. Most people just know it for some small amounts of controvesy it caused.
Adults know GTA, ALL teenagers I met know GTA. As in all of them.
CoD... its different. MOST teenagers or youung adults know it. Many parents and adults (that arent gamer I should have stated earlier) know it.
All in all here is how it is in my country:
Most well known in no order:
World of Tanks ; Counter Strike ; Diablo ; TF ; DOTA ; Warcraft and Starcraft
Slightly less well known, but still popular:
GTA ; Call of Duty ; BF ; NFS ; FIFA
Well known, just not as much as the other categories:
TES ; STALKER ; Crysis ; C&C
And after that put the other games
