This was a really smart, interesting and clever plot game. I thought overall Portal was a good game, but it needed more of a story-line and less repetitive test chambers. Which is exactly what portal 2 did. I personally enjoy for gameplay and story-line Portal 2 over Half-Life 2. I'd say Portal 2 is in my top 5 favourite games of all time.
