CMS style, fill and publish. The only characteristic that I find more complicated to achieve is that it allows me to do it multilanguage. I would like to have two versions of the page, in English, and in my language, and the user can choose the language. I would write both versions.

Maybe Wordpress with modifications?

PD: I really don't know in which category to put this thread.

I'm not sure either what the question is.

If you want to create a multilingual webpage about game study, then simply create two files, index.en.html and index.xx.html. Apache can be configured to serve these according to the Accept-Language HTTP request header. No need for a dynamically generated page (and Wordpress needs a scripting language running on the server-side).

If you want to create a game study on a webpage, then here are a few frameworks (mostly Javascript) which you can use. But these all require programming, there's no such thing CMS based game (unless you're creating a very boring text-based adventure game with "if you want to do this, click here" options at the bottom of the page). Also these run on the client's side, and Wordpress is a server-side framework.
