Wii Warm Up: Favorite franchise?

We've been askingabout your favorite entries in big Nintendo franchises (and we probably will again!), but we thought we'd ask a more macro-scale question. What's your favorite franchise on Nintendo consoles? You've got your Mario, Zelda, and Metroid, obviously, but there's also Sonic, Resident Evil, Mega Man, Street Fighter, and years and years of other series throughout history. And don't forget about the comparatively newer series like Super Monkey Ball and Phantasy Star Online!

As for us, it's definitely Castlevania. We have been faithful to Konami's pseudo-horror series since the very start.
