HalfLife.. easy. halflife 1 whas (back in it his own time) a GIANT hit. it elevated the fps genre. (im not a big cs fan so i didn't vote because of that )
It was a very hard decision. I was with threee choices: Final Fantasy, Half-Life/Counterstrike & Halo Series. I took Halo out because all you do in Halo is fight, no puzzles. Then there was FF and HL. I enjoyed every expansion pack for HL and CS. FF was all fantasy, I was judging by succees but because my personal got into it, I voted... HALF-LIFE
I loved Half Life 1 that GMV. Half Life 2 was very cool also but mainly because of Half Life 1. I would've picked the Doom series over HL tho.
I had trouble deciding between Super Mario Series and and the Final Fantasy series but i voted Super Mario Series as is it just gave me so much fun and good memories of when i was lil teeny weeny kiddy.
voted halflife both games were a big hit.. and the FREE mods that you can play on them are also really good.
man the zelda series was so tight man i remeber being a lil kid on christman morning when i first got that game took me a week to beat but i never slept and if i did i feel asleep playing that game was so sick i miss playing that i think that i am gonna go out and buy that game along with nintendo 64 . -AlmightyWhity-
