awesome! it change the way I look at console FPS games.
As for the 5 games in one:
1) I like the story line beind half life 2, episod 1 and episod 2. This alone is woth the $$. Awesome value just due to the fact it will take you forver to finish (huge game) and you'll be happy with it.
2) Portal is one of the biggest surprises, and a gerat addition. An on-line protal would have been cool.
3) Team Fortress 2 is different that what I'm used to in my PC's team deathmatch. I'm not sure what to thing of the cartoon'ish display. I think this is just due to the fact I'm an oldschool half_lifer. all in all, I like it!
The only thing that I could ask for would have been gary's mod :) but I feel bad even asking for more in this game.
