What game series is best??

I've never played Mass Effect, however, one game series that I believe would count is the Bioshock series.

Bioshock 1: I'm not normally into scary games but something about this one was different, it had a plot. There was reason for all this madness, and it was a good reason at that. The world of a fallen Atlantis was very interesting and the man behind it all was even more so interesting. There was a sort psychological aspect to the game. When you see the big daddies you have to wonder if those Leviathans were going to hurt you, but no instead it's up to you to decide that. Furthermore, the morality behind your choices, whether to help the little sisters or mutilate them further by taking their eve. The conflict that you felt when deciding was intense. Then there's the whole idea that you can sympathize with Andrew Ryan, "the bloody king of Rapture." This man was clearly ambitious, he had a dream and he achieved it. You can't help but at least admire that. Then there's the twist ending. The hero of rapture and who he really is. That's the thing about the game, the minor details tie into the overall story. If you look around you'll see posters of Atlas, the proletariat trying to save Rapture. But that turns out to be not as true as it would appear. Even more so the recordings left behind gave you a sense of the characters, how Tenebaum regrets her decisions, and even how a weirdo like Cohen regrets going to Rapture. Overall the world was well-developed, the game mechanics were great (magic in one hand, gun in the other), and the story was amazing.

Bioshock 2: This one, I'll admit, was not as good as the first but it still, in it's own way was a good game. Granted the aesthetic of Rapture was sort of lost, but the story wasn't bad. You got to see what the Ryan's rival was like, Sofia Lamb. How she stood up to Ryan and the extents to which she went to defy Ryan. The character that you play as is tragic and I love it. This game is similar to the first in that the game mechanics are the same, the setting is the same, but the story is different. The whole time you're character is searching for Sofia's daughter, your little sister. One aspect about this game that I like is that they explain what to do with the little sisters once they stop being so little and the result is scary. The recordings in this one aren't so bad either. There's still that gray morality tied into the game. But I will admit that this game, while it did feel like a sequel, was a bit repetitive. However, overall, this game wasn't bad and it did tie into the first in an interesting way. It added to the series nicely.

Bioshock Infinite: This in itself is a whole new game and could easily be titled something different. Although it has Bioshock slapped on the title. I will admit that this game didn't meet my expectations, and it was kind of a let down. But in it's own way it was a good game. Actually that's all I will say.

Overall, the Bioshock series is a great franchise. And I admire the people at Irrational games to develop something like this.
