I mean, saurworld.org is a news/blog site for this game: http://sauerbraten.org. Can't really blame them for assuming their readership knows what the game is.
As a rule, landing pages for online communities should have some type of link to a "Wait, what the hell is this stuff, and why should I care?" page.
Willing to bet a fair number of folks found this, figured out it was some kind of game, and immediately wanted to know more (I certainly did)... but had to dig around to do so. "Sauerbraten" is a very common German dish, for which every search engine (correctly) returns a big list of recipes.
I was looking for the information, too. But luckily, it wasn't too hard to find: you scrolled to the bottom and in the footer it says "the game" which includes a link to the game website.
Turns out Sauerbraten is a free multiplayer & singleplayer first person shooter, the successor of a game called Cube. Here is a youtube video of the gameplay https://youtu.be/fX7o-1OH-WM
