A lot of the audience probably is the nostalgic. But also, there's quite a few genuinely good games in there, and also some very foundational ones. The tendency towards cartoony graphics and a plot/humor focus means that in some ways they've aged a lot better than other games from a similar era. In a way it's like asking why people read old fashioned novels, even though they're out of step with modern language and culture.
