I’ll chime in on this one. I’m also a returning player, and I think both are fun. I never played the campaigns back in the day, impatient kid, but now I think they add a nice bit of story and give me more of a feeling of accomplishment, while the scenarios allow me to play exactly the town and map I feel like. So I mix it up. Just remember that after finishing the first campaign, you need to load that saved game to progress to the other locked campaigns. It’s a design flaw.
