I LOVE Portal, haven't gotten Portal 2 yet, but do plan on it sometime in the near future. 2 of my grandkids love watching me play it (because I don't allow anybody on my computer, they only get to watch

) just about every time they come over.

It really is, in my opinion, a very unique type of game, and very engrossing. VERY funny dialogue, and the different ways of solving the puzzles makes it very replayable, just try a different way than you previously did it.
