ya know . i have not found a game that i play more then 1ce or twice , except half life and all its expansions. this game and every part of it (half life , blue shift, opposing force, decay , and then half life 2 , ep 1 and 2 ) i have played consistently every year since their release. cant get enough of this awesome game. portal and portal 2 are also very re playable . it takes time to create such perfection. every time a half life or portal game comes out they revolutionize the gameing industry and valve can afford to sit atop its throne for a few more years smokin cigars cuz for real they are that good.

i dont wait for those games to come out, i just continue life and get the next one when it does come out.
