Right but it was all IRL video. I mean, I get it, the guy was supposed to be a guy in the game and all. Just think its quite strange that they used 0 gameplay in it. Its Bethesda so its going to be great, just a strange way to go about it.
They have been doing stuff like that to announce games for a while now.
Ads such as this are done to gauge player interest in the game idea.
Its kinda like the ad for Cyberpunk 2077. It shows no gameplay, but the idea is really exciting and the gaming community responded strongly to it. LINK
