What is the greatest computer game of all time?

I am trying to determine the greatest game of all time, it can be from any genre, any platform, any year. Unlike the lists in magazines created by so called "Experts" this list will be created from your votes. Anyone can fill in the greatest games of all time survey. Obviously i would like you to all stick around the site but its not compulsary to.

The scoring is set up like this seasons F1 scoring system with 25 points going to your favourite followed by 18,15,12,10,8,6,4,2,1 in order. Please vote for your favourite games, not games you tink should be there or leave some games out because you think loads of others will vote for them.

The survey can be found here: http://thenewhut.com/site/pg/quiz/do/the_greatest_games_of_all_time

Thank you for helping out
