The games have not aged amazingly well in the intervening years from a technical standpoint especially the first one. As for the Storyline its talked about because it's so damn weird. It one of the first real niche Japanese titles to make it's way over intact so that could be a major reason people remember it really…

OH HELL YES! Depressive storyline without hope for happiness or comprehension, here we go!

I'm surprised so few of the women in the series are playable in this game though. There are definitely some more major ones that could be featured, like Lisa Lisa, the mentor from Part 2 who went on to inspire Rose from Street Fighter.
