I like how RBY didn't heavily rely on "the power of friendship" or being forced to like a character because they appear throughout the game. All you need to know is that you're just a kid on an adventure and competing with everybody else. There's none of that sugary goodness where everybody is nice, and your rival is even a dick to you.
That, and also funny RBY quotes. When I just want something to laugh, I just look at the most memorable quotes from that game.
