Xenoblade, Skyward Sword... I'm detecting a pattern in my recent gaming history here. It's no surprise when a game chooses to name itself after its signature weapon, since everyone thinks swords are neat. Though, as the recent MBMBaM (91) podcast explains, they're not quite so helpful in a world with SMGs and sniper rifles, unless you're being home-invaded by The Kurgan or something.
So far this is just a smattering of notable games with this naming convention. There are TONS of these things.
