For Science.

Only about four years late to the party, i've finally started playing the first Portal. I've seen it played through and i just watched my boyfriend play through all of the second one. They're puzzle games, and the writing is so clever, so they're fun to watch, but apparently even more fun to play!
I've got the first one on Steam but i think i might have to go ahead and get Portal 2 on PS3 for myself.
