I've only ever invested a great deal of time and energy into The Legend of Zelda . I also like the Super Mario franchise, but I am not too keen on the side-scrolling games. It's not that I don't like them, it's just that I suck at them. The only ones I'm good at are a couple of the spin-offs like Yoshi's Island and Wario World (or whatever it's called). I've dabbled in the Metroid series, having played the first two Prime games, but that's about it. Oh, and of course there's Super Smash Bros.. With that all being said, I guess you can say that the only franchises that I could never get into are the ones I didn't mention above. However, that's not to say I actually tried the games and didn't like them; it's just, I was never allowed the opportunity to play them.
