Safest: click on the links to the game page directly and download from there. Usually itch.io, patreon, subscribestar, etc.
Safe: downloads from the main page directly.
Less Safe: Download the files given by users in the threads.
Viruscity: Click on and download any programs from the ads that pop up during the attempts to download from the 2nd or 3rd options. If you are not downloading a file that is literally called game-version.zip or something similar it's not what you want.
But around these parts that's the price of doing business. Who hasn't gotten a cybernetic std when sleeping around game pages.
