BioShock vs BioShock Infinite
BioShock
BioShock is one of the most highly acclaimed steampunk-themed shooters that has a very interesting twist - your very character's DNA can be modified through the use of a selection of plasmids and a special resource called ADAM, allowing you to have superhuman abilities which will serve you well, sometimes more so than the weapon you wield, in your adventure through the fallen underwater city of Rapture. Aside from the many violent mad men (a.k.a. Splicers), the game also provides players with challeging encounters with the iconic Big Daddies and Little Sisters.When it comes to non-military-styled shooters with an intensely immersive storyline, BioShock is among the handful of the "best of the best" (which includes the Fallout series, the Borderlands series, the Deus Ex series and others). The game boasts of having a rather dark storyline that actually challenges you to think about it in a more in-depth way; to link all the clues together to get the complete narrative that is surprisingly a lot more engaging that you'd expect.
2K Games has just released the remastered version of the very first Bioshock last year and if you can get it on Steam, you really should. The very unique experience it can offer you is very well worth the cost.
BioShock Infinite
BioShock Infinite is the last sequel of the BioShock series and is possibly the best one (or worst, depending on which side of the coin you are at) yet. The game is set in a gorgeous and populated city (at least at the beginning) in the sky called Columbia that unfortunately is not as cheery it apparently seems. The gameplay is quite different too since you'll have access to the city's many ziplines via special grappling hooks called Sky-Hooks, tears in the fabrics of time that you can exploit during combat to pull in aid in the form of turrets, weapons and other resources; as well as more Vigors.Not many people like this version of BioShock for their own reasons, but everyone can agree that for what it's worth, this game shouldn't be the end of the BioShock series... but that was what happened. So, if you're a fan of the franchise, this game is definitely a must-buy, just so you can enjoy the unique flavor of your favorite series one last time... and also to get your mind blown to pieces figuratively when you eventually realize how well the story is rounded up with that rather befuddling ending.
