The real product being advertised here might just be Blender itself: Alex Martinelli, known for his Geometry Nodes-powered projects, has now recreated one of those sketchy game ads fully with Geometry Nodes as well.
Alex mentioned the entire project took just 2-3 hours to complete. "With intermediate knowledge of Geometry Nodes, this isn't too hard, it's just not something many would think to try," commented the developer.
