DOOM having stairs and up/down movement, and vertical elements to the level design was really revolutionary at the time.
This. After Doom, there were maaany releases where a studio had X out there, and then released [3D version of X]. Or also throw themselves onto the fps genre. Almost to the point of killing innovation.
Don't get me wrong: that, and the 'infinite' storage of CD-ROMs got us many nice games.
But neither did much to sharpen game developer's creativity skills. Many "me too! (meh..)" releases in that era.

More unhinged fun IMO
Tank Wars came out in 1990, Tanks came out in 1991.
There were artillery games before Tank Wars, of course. But none, to my knowledge, had AI players and insane weapon purchases, which is what made the game really fun, and which Scorched Earth inherited.

Rollers! Lava! It’s like the author started with a simple tank war game and then just threw in every weird little effect they could code as a creative weapon.
There were all kinds of neat hacks.
years later i defeated the high score of Stephen Meek and realized with horror Oregon Trail was intended to teach patience not just dysentery damn you MECC!!
