BioShock vs Silent Hill
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.
Silent Hill
Silent Hill is the first game in one of the biggest horror-themed adventure game franchise. This game lets you join Harry Mason, the average concerned father, who based on a clue he obtained, went to the mysterious and eerie town of Silent Hill in search of his missing adopted daughter, Cheryl. However, things took a turn for the worst when Harry stumbled upon a cult that is trying to revive an evil deity it worships and discovered the origin of his daughter. Being an adventure game, Silent Hill also offers multiple endings depending on the actions you take and the decisions you make in addition to an engrossing story.Konami has also reinvented this classic and produced a remastered version of the game, called Silent Hill: Shattered Memories, for Wii, PSP and PS2.
