Having trouble downloading a forum thread with wget and httrack

I'm a big Civ IV fan, and I'd like to download all of the Sample Game threads on this Civfanatics site: https://forums.civfanatics.com/threads/sample-game-directory.258697/

I'd like to have all of the posts and images from each sample game, each of which is a forum thread with multiple pages, posts, and images hosted from elsewhere.

Here's the wget function I tried (which I mostly stole from here https://letswp.justifiedgrid.com/download-discourse-forum-wget/) :wget --mirror --page-requisites --convert-links --adjust-extension --compression=auto --reject-regex "/search" --no-if-modified-since --no-check-certificate --execute robots=off --random-wait --wait=1 --user-agent="Googlebot/2.1 (+http://www.google.com/bot.html)" --no-cookies -r https://forums.civfanatics.com/threads/sample-game-directory.258697/

It gave me an index file that was way too small, and while it did take me to the index page, seemingly locally on my system, clicking on any of the forum threads took me to the actual website instead of a local mirror. Also I don't think any of the images (which are linked from elsewhere) downloaded.

I'm mostly just interested in a subset of the sample games, so I'd be fine downloading each sample game forum post separately, but I haven't been able to do that either.

Any help would be appreciated!

Edit: I also just tried httrack with no results either:httrack "https://forums.civfanatics.com/threads/all-leaders-challenge-game-strategy-session-montezuma.168755/" "+https://forums.civfanatics.com/threads/all-leaders-challenge-game-strategy-session-montezuma.168755/" -v
