1990 Mega Drive games

1990 came in the wake of a shoot-'em-up game craze spurred by the success of shoot-'em-ups by arcade developer Toaplan and home computer developers Compile and Konami, and the Sega Mega Drive was far from exempt — a majority of the third-party games released in 1990 were shoot-'em-ups. However, Sega themselves (as well as a handful of third-party developers) continued to make games in a variety of other genres.
