Valve has made some amazing games that are not to be forgotten, ever. The games Valve is the most famous for are without a doubt Half Life, Portal, and Team Fortress/ Team Fortress 2 and the excitement level people get from these games is through the roof, piercing the stratosphere.
Finally, they combined their 3 greatest, most successful games in one ultimate, must-have game bundle. With the Orange Box you get Half Life (Episodes One and Two), Portal, and Team Fortress 2 at the price of half a regular game ($30) for any console and only $20 for the PC. If you're looking for action, adventure, some comedy, and especially quality then this game is for you.
I personally own this game for PS3 and PC and play both for at least 2 hours a day (that English paper can write itself!) Although there is much more customization available through the PC version, the PS3 version just adds more bang for your buck.
Graphically this game definitely meets the high standards of 2008-2009. Although cartoonish, Team Fortress 2 has excellent graphics and is my favorite fps out there.
The sound quality is also top notch and personally, those comments on TF2 (Team Fortress 2) can crack me up.
As for the PC version Valve constantly updates every one of its games sometimes adding new features and weapons whereas the PS3 version does not get many of those upgrades.
Overall this game is amazing and 100% satisfactory. Therefore, I recommend this to anyone reading this review and urge you not to waste any more time.
