i beat portal 2 this morning by the way. pretty good game. i liked the story a lot. the gameplay additions were pretty sweet too, but i still think i like the original portal more for two reasons.

1) shorter run time. i just like shorter games in general.

2) it felt like you could break it more. portal 2 sometimes had invisible walls and stuff where i could clearly break something using the physics but the devs just said no. i like the freedom of portal 1 more.

4/5, solid game. on to half life 2.
