Yes correct. I tried both and was annoyed that the zombies aren't deadly enough. Like "oh we have this serious virus but you can survive getting bitten multiple times"
With the idea I wanted less of a story (and let's be honest both games and their successors did not have good ones) and more of interesting escape attempts (find a drill and move underground, or dress up as someone from the military or idk get catapulted with a parachute)
I know all the games you have listed. I havent played them but I can tell that none have the features that I am looking for.
Prohect Zomboid comes close in terms of environment but has a different gameplay approach.
