Better deal than ANY game!
The Half-Life Series changed gaming with it's insane graphics and gameplay! Now, you can play the three Half-Life 2 games on the Orange box. But that's three games. The other two are insanly fun as well.
The biggest game in the Orange Box is Portal, a fun puzzle game that has you creating doorways that you create to get past different puzzles. GlaDos is the best character I have ever seen with her sense of humor and yet suprisingly freaky mood swings.
The last game is called Team Fortress 2, fans of the original will especially love this game. The classes are back and new maps are here, but that's pretty much it.
So what do I think about the Orange Box? It's a solid 10/10. I don't play Team Fortress 2 that much, it still is quite fun, but the main reason that I got the Orange Box was the Half-Life 2 games and Portal.
