Depending on how you define "town building", there's a ton of survival games on PC that would count. Stuff like Valheim or Enshrouded or Medieval Dynasty. Conversely, games like My Time at Portia/My Time at Sandrock.
ActRaiser is the classic oldschool example, but Suikoden might count as well because those games always involve you building a base/town up from ruins into a major fortress town.
A lot of it depends on how deep you want the "town building" to be. Most games just have the towns produce resources, establish stores, give minor stat benefits, or allow for NPC interactions. Nothing as deep as you'd see in a game like Civ (or even SimCity) where you're controlling things on a more granular logistics level.
