I played WoW when it came out but I thought even then it was clear that their adverts and cutscenes weren’t trying to fool us into believing that was the gameplay. I can’t speak for StarCraft, but in WoW they were labeled as Cinematic Cutscenes. Most mobile games ads i see are made to look like gameplay, even the picture OP posted.
Lol the least splinter cell like level in the series(still a fun level)
