Best Game of The Orange Box?

I'll say between Portal and Half-Life 2: Episode 2.

The Orange Box.

Edit: ... This is why I shouldn't do two things at once. Team Fortress 2.

I'd say TF2... but this is the Xbox board. So HL 2 or Episode 2 I suppose.

I love TF2.

i bought OB for Team Fortress 2. I was blown away by the cartoony graphics, animation, and weird character classes.

I still play TF2 to this day. Clocked in a total of 400 hours (150 hours JUST as the engineer! yippity-yeah-kee-aye-yoo!)

Team Fortress 2 is my favorite multiplayer game and I played it for around 900 hours.

TF2 is the best online game this gen imo.

Episode2 would be my fav of the singleplayer games though (with Portal and Half LIfe2 jsut behind)

Portal with TF2 coming in a close second.
