Ars Technica closely examines some recent games that raise controversial themes and issues.
On Super Columbine Massacre RPG!:
Essentially, SCMRPG! is a psychological examination of Harris and Klebold. It attempts to put the player into their mindset, exploring how and why they came to do what they did. The subject matter itself questions what a game is meant to be. Though people normally play video games for sheer enjoyment, there is none to be found in SCMRPG! Instead, I found myself actively dreading entering the game world, unwilling to perform the actions necessary to progress.
On Metal Gear Solid 4:
In the world of MGS4, war has become a business, and PMCs are in the center of it. The new war economy means that the world is in a constant state of battle, locked in perpetual proxy wars fought for business purposes. But while this is an interesting concept to contemplate, unfortunately it is not covered with real depth.
As a Kojima game, MGS4 spends much more time tackling strange philosophical debates than it does real world issues like PMCs. And given the fact that the existence of these corporations only came to light recently, it's a topic that is at the forefront of many people's minds. The game is wonderful, but the opportunity for a serious look at the subject was squandered.
