The original Raiden, developed by Seibu Kaihatsu and published by Tecmo, came out in arcades in 1990. This handheld conversion wasn’t released until 1997 – well after Atari had discontinued the Lynx. And even then the game was only available by direct order, and through a few select retailers. It’s still available to buy now, at the time of writing.
A notch above “Monkey Tennis” in terms of great ideas, Ninja Golf was dreamt-up and released for the Atari 7800, way back in 1990.
I can’t write about the other Shadowrun games without mentioning the Sega Megadrive/Genesis game, first released by Sega in 1994.
