The Orange Box is the BEST investment you can make in gaming. It includes 5 great games, Half-Life 2 (episode 1&2), Portal, and Team Fortress 2. There is nothing bad that can be said about this bundle of games, because its all for the cost of one. No disk swaping, everything is on one disk. And the games are great, really great. Half-Life 2 is my person favorite game of decade and the episodes continue that. Portal is one of the most innovative video games of all time. And Team Fortress 2 is a fun multi-player game to waste some hours with.

The only bad for each individual game are..

Half-Life 2 there is nothing bad.
Episode 1 is too short and doesn't advance much story.
Episode 2 is short, but still awesome.
Portal is way too for how fun it is.
Team fortress 2 is just an average game.

But they are all must play for anyone.

Valve does it again with a gift to all gamers.
