I won't go into details what TV Tropes (http://www.tvtropes.org) is, in case you all already know.
If you don't know, it's fairly big (https://www.similarweb.com/website/tvtropes.org).
"Creeper World" (http://tvtropes.org/pmwiki/pmwiki.php/VideoGame/CreeperWorld) page contains a decent number of references to CW1, but it diminishes rapidly for 2 and 3, and had no mention of 4 (all games share the same page, at the moment).
I have added a number of tropes for 4 over the last couple weeks, but didn't have a ton of time to work on it. Also my English still has quite a few problems.
Consider contributing to the page, as well as adding Trope->Work examples.
TV Tropes can be a great way of attracting players. I have discovered quite a few games there myself.
Let's make sure that the CW series has the representation it deserves on that site.
