Overall it was the most creative game I've ever played, the people at valve outdid themselves. I got it as part of the Orange Box, which is the best game I've ever bought.
Portal was good exept everyone freaks if you say " COMPANIONE CUBE SUCKS!!" and things like this, only losers waste their lives on lv 16 (i think thats the lv) with the weighted companion cube its so retarded nothing special about it, at all. but other than that great game loved it xD
