What are the MUST OWN TG16 Hu-Cards?

[2Dskillz]

I am new to yet another system (when will this sickness end?) Any way I want more games to go with my new TG16, but of all the systems I have dipped into this is the one I am most at a loss for. I enjoy a bit of everything...so what is the best?

Keith Courage in Alpha Zones. Literally "must own" unfortunately.
