Worms is in the same genre as Scorched Earth and owes it a lot for inspiration, but it adds a ton of distinct weapons and movement technique that certainly qualifies it as it's own game.
Yeah! This genre is called "artillery games" [1] and it has an impressive number of titles going all the way back to 1972! Scorched Earth is at least the 16th game in the genre, albeit the most famous pre-Worms.
My favourite iteration growing up was called Dome Wars [3] and it's not even on that Wikipedia list!
