You can also see the occasional great-grandfather game being referenced in homage to their likely inspiration.
I consider it likely that a number of these references will be completely overlooked and perhaps feel out of place soon, due to popular culture changing over time.
That almost makes it look like games are made to be forgotten later down the road, concentrating less on producing something original and memorable while leeching off of others' success instead.
One might say these references are to pay tribute to things that influenced the developers throughout making the game, or to things they cherish and feel the need to praise in such a way.
I'll admit I'm guilty of this: The game I'm working on has dozens of references, some of the levels actually have their story plugging a game genre or TV show. When I think about it, these references came to me somewhat along the lines of "haha yes let's do this, it'll be hilarious, I love <insert name here>". Ready your tomatoes.

Do you think people are trying to make up for their lack of creativity? (even if not consciously) Is it likely that many would use them to get some cheap laughs and smiles to boost their marketing?
