I'm very fond of both and they both have a special place in my heart because I grew up with them.

I've played far more Mario games than Zelda games. And growing up, I played them with my siblings. They're very fun group games, so I don't play Mario games alone much.

Zelda games, I play alone for the most part. I haven't played as many as I'd like, but they're all really high quality games. Since I'm more of a personal gamer than a group gamer, I do enjoy the Zelda games more.

I voted for Zelda.
