1. The Legend of Zelda
2. The Legend of Zelda
3. The Legend of Zelda
4. The Legend of- NAH, I'm just kidding.
Though I did genuinely think about putting that, because on the whole Zelda is the only real series I like... I mostly tend to play one-off games, or I only actually like one of two games in a series, not the series as a whole. But I suppose, if I had to make a list of favourite series is would be:
1. The Legend of Zelda (no surprises there)
2. Mario Kart (hands down one of my favourite multiplayers, with added nostalgic value)
3. The BIT.TRIP series (One of the rare exceptions, apart from Zelda, where I love each and every game in the series... they're all ridiculously fantastic and addictive games! Ad if you haven't already, you really need to try them)
4. Sega Megadrive/Genesis Sonic the Hedgehog games and Sonic Advance games. (I'd be lying if I said the series as a whole, since I hate most of the 3D Sonics... urgh)
5. Pikmin and Smash Bros (about on par, and there's hardly enough games to call them as series on their own, so I smushed them together in number 5 spot).
Now, now before I get lynched, yes I have played Pokemon/Mario/Kirby/FF, but like I said only one or two of the games actually appeal to me, so it isn't fair if I list them as liking the whole series when I don't technically. And since this is a list of my favourite series, there's no point listing them. And sadly, call me a no0b, but no... I've never played a Metroid game in my life, though I definitely plan on picking one up some time...
And yeah, I know they're mostly Nintendo series, and I've not been around the pond much, as it were... but I'm not bothered, Nintendo make great games and that's good enough for me =D
