Everytime you search for anything about Halo 3 on Google, Halo Reach is also highlighted. Google thinks Halo Reach is just an expansion of Halo 3, which is not true since Halo Reach is a full game.
Strange I Googled Halo 3 and I get no search results for Halo Reach, even when using the link you provided. But since the word “Halo” is one of the key words you searched, then why wouldn’t it also highlight Halo Reach? The word is right there in both titles.
uhhhh idek what to say
