Quoted from chuckwurt:Portal absolutely blew my mind when I played the first one. Portal 2 was even better with the Co-op mode. Hopefully there is a portal 3 in the works. SO MUCH FUN.
yep both Portal and Portal 2 are up there for best game ever for me. (along with Grim Fandango, Shadow of the Colossus, Civilization 2, aaand i dunno, let's say StarCraft.)
GladOS is definitely my all-time favorite villain.
JK Simmons as Cave Johnson was just plain brilliant as well.
and of course Stephen Merchant was hilarious as Wheatley.
