Winter!: Prepare for holiday gaming!
I can't tell you how many times I have beaten Portal between systems. It never gets old, even though I have all the puzzles memorized. GLaDOS never grates on my nerves...I even know how to capitalize her name properly! Portal is a truly great game that is only trumped by it's sequel, which is an even greater game. The extra challenge rooms that come with the Still Alive edition are a bit "eh", however.
