7. The Xenosaga Series: "Der Wille Zur Macht," "Jenseits von Gut und BÃ¶se," "Also sprach Zarathustra"
What's the only thing stranger than using the adjective "Final" in the title of your long-running RPG franchise? Did you guess using pretentious, untranslated quotes from Friedrich Nietzsche? If so then you are NUMBER ONE BIG WINNER! I like to imagine that if you were hanging out with all the RPGs you've ever played at a party, Xenosaga would be that weird kid from your philosophy class who just wants to argue with you about religion. Why won't he just leave you and Chrono Trigger alone???
6. "Melty Blood"
Apparently based off a Japanese visual novel (i.e. a super text-heavy Japanese videogame) called Tsukihime, this fighter was reinventing ways to hate vampire fiction back when Twilight was just a sparkle in Stephenie Meyer's eye. The game itself deals with the characters search for a legendary "True Ancestor" who they believe can cure vampirism. I haven't actually played it, but I'm assuming that this "ancestor" most likely has blood which for some very specific reason is "melty," and if you beat the game you get to find out what the hell any of that even means.
5. "Touhou Seirensen ~ Undefined Fantastic Object"
Touhou is a supremely Japanese game for not one, but two reasons. Number One: it belongs to a genus of mostly Japanese-only games known as "Bullet Hell," so-called for the fact that you must pilot your sidescrolling lasermaker through gaps in enemy fire that are at times only a pixel or two wide; and Number Two: its insane fan base has helped it to spawn dozens of sequels and spinoffs spanning various genres. I highly suggest checking out the Wikipedia page, because each title in the series looks like it was ripped straight from a glitchy captcha box.
