A bit misleading marketing there (like always) - all the good looking game videos are actually just AI generated videos (obvious tells: HUD elements wouldn't have scrambled text if they were actual games, rendering of barrels has the worst LOD popout I've ever seen or it's AI), but the actual games are really bad.
