Here is a brief summary, but the short version is that it contained a lot of historical falsehoods and seemed designed mostly to make white people feel better about racism.
I think suggesting that people don't like the Oscars just prefer blockbusters is unfair. In most years (they
have got better recently) it's not hard to predict at least one movie that will likely get several nominations despite not having particularly good critical reception; Hillbilly Elegy, Bohemian Rhapsody and Green Book are a few recent examples. The fact that this is so easy to predict is where the term Oscar-bait comes from in the first place (from what I've seen, it's not usually used just to refer to any independent or non-blockbuster film).
On the other hand, this doesn't really happen for TGA. Part of that is because AAA games tend to review at least decently, but if you look at the entire history of TGA's GOTY winners, I would say most are pretty deserving, with the exceptions for me being Overwatch and Dragon Age: Inquisition (and I only say that due to a general lack of interest in multiplayer games and a lack of familiarity with that game, respectively).
