I think you are confusing the terms famous and popular here. I doubt those "games" are the ones leaving a lasting impression on culture and industry. Specifically made for quick consumption and recycling, mass-produced and expendable, they are purely commercial in nature. The goal of these games is not to leave a legacy; rather, it's to grab a quick buck and provide a stream of content to keep the cash flowing in. In a way, like Starkurt pointed out earlier, they are very efficient and straightforward. They provide a zero-effort quick fix for those who want exactly that. The same situation as with music production: pop music is the most popular thing, but not the most creative, advanced, or influential. Few songs are remembered after a year or two, because there are always new ones. Now the question, why so many people choose to engage with the medium through the lowest effort route, is pretty simple. They just don't care; it's very low on their priority list. Time of their life is occupied with other things, and whether or not there is a good game they can play doesn't matter much. The only people who actually care about quality and creativity are those who either want to create games themselves or those who don't have much else in their lives to turn to outside of their favorite games. Basically, the number of local residents is always going to be lower than the number of tourists, and the tourists like buying shiny baubles.
