Honestly, one type of gaming industry that people overlook is the AA industry (not to be confused with the AAA), and hobbyist games (not to be confused with indie games). People in those 2 industry make good and interesting games, but most people talk about indie games being better than AAA, and ignoring AA and hobbyist games.
With the state of gaming going, it makes me glad that I mostly play games from the 2000s to early 2010s. Most aren't for nostalgia reasons (in fact, I was a baby in 2000s, and a kid with only a Wii in the 2010s), I played a few fun PS2 games when I bought that console a few years back. Currently only have 5 PS2 games, and one is said to be bad, which is why I bought to make a game review for it (which I haven't started yet)
