I don't understand. Even if you think the games are overrated, it doesn't mean you can't like them.

Look on the bright side! It's technically winning!

The worst from the poll is a tie between Mario, Zelda, Donkey Kong, Smash Bros, Mario Kart and Halo. Yes, i hate Nintendo games. I don't hate Nintendo, but i REALLY dislike their games, and trust me i've given them a chance.
Worst series in my opinion that are not on the poll (hard to name just one): Final Fantasy, Monster Hunter, Pokemon, nearly every JRPG (except Yakuza), Pikmin, Metroid, Yoshi, Kirby, Fire Emblem, Animal Crossing, Sonic, Mega Man, Street Fighter, The King of Fighters, etc.

Man, that's really a different opinion!

Of those ones listed GTA. But there are a ton worse than any of the choices.

Wtf how dare people voting Uncharted?! The best adventure serie in my opinion.

I voted for Halo.

What do you like? The Last of Us?

OT: Most of the worst games aren't actually made into a series. However, I would wager that the Petz games are pretty horrible. They are a (bad) knock-off of Nintendogs, which isn't the best game anyway.

I'd say Mario. I mean I love 3d Mario games, but I think the last few 2D ones have been mediocre at best.

Of those in the poll, I'd say Uncharted. I've played all 4 entries and While I think 1 and 2 are awesome, 3 and GA are mediocre IMO.

In general, it'd be the Fifa series, really boring games IMHO.

I hate CoD with a passion and that's it. I have no quarrel with any of the franchises in the poll but for the sake of picking, Zelda. I don't find the lore interesting or its confusing plot line.
