BioShock vs Thief 2: The Metal Age
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.
Thief 2: The Metal Age
Thief 2: The Metal Age is the highly anticipated, award-winning sequel to the incredible, stealth-based game, Thief (now called Thief Gold). This game features 15 new, non-linear and complex levels filled with tons of stuff to steal and guards to outwit. The AI in the game has been drastically improved as well, along with the addition of new tools to use and a compelling storyline set in an alternative world where powerful technologies and fanatical religion streneously co-existed.Despite being a rather old-school game, you can experience why this game franchise has blown up back then. Its stealth-based gameplay is pretty awesome and the plot is the best in the series. It is actually this second installment which had inducted the Thief game series into the coveted games' Hall of Fame!
