I mean, yes, but Liero means "worm" in Finnish, according to the wiki.
Just trying to understand how these games evolved from each other (or not) for the sake of video game history :) I loved Worms when I was a kid, and wish I had discovered Liero back then!
Yeah, I know (am Finn, and played Liero a lot when it was first released). And sure, it’s not exactly wrong to describe Liero as "Worms but in realtime".
However, Liero was inspired primarily by another Finnish SW game Molez, the titles sharing two defining gameplay elements: realtime and digging. Like moles, worms live underground and dig tunnels, so they were a natural animal choice for a Molez clone.
The ninja rope in Liero, of course, is straight from Worms though.
