Yeah, that's one of the earliest ads for TG-16 that started showing up in gaming magazines around August 1989. As you can see, Legendary Axe, Victory Run and Keith Courage were the main three games featured.
I'm starting to think that with the first test launch, there was only 3 games. Then, when people around the country could start to get Turbo's, I think there was a second wave of software that arrived then.
Kinda like two different launches. Maybe if you were in New York, initially, you could only buy Legendary Axe and Victory Run individually. Then, when the TG-16 launched Nationwide, that's perhaps when games like China Warrior and R-Type and Dungeon Explorer, Power Golf, etc, etc also arrived.
Of course, this is just a theory right now, and there is a wee bit of evidence pointing to this theory being plausible. but I need some better corroborating evidence to really lock down this possibility.
