Best Game of The Orange Box?

I'll say between Portal and Half-Life 2: Episode 2.Best Game of The Orange Box?
I haven't played episode 1 or 2 and haven't beat Portal just yet, but I'd say TF2, love it.Best Game of The Orange Box?
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.
Portal; it's the only one I'll still distinctly remember 10 years from now. This would have been perfect for a poll thread; 5 games, 5 poll categories.
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!)
I like them all but the two episodes of half life 2 are the best. I still play TF 2.
Portal for me. I wasn't really able to get into HL2 and subsequently haven't played any of the episodes.
Portal hands down.
Half -Life 2. Not only the best game in The Orange Box, but probably the best FPS ever made.
Portal is highly over rated imo...the first 17 levels might as well be tutorials...
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.
TF2
