Yeap, GTAIV is finally a record holder in the Guinness Book of World Records, breaking the previous record held by Halo 3 in overall revenue sales within the 24 hour mark of the game's launch. It also has attained another record by being the fastest selling piece of entertainment software, selling 3.6 millions on the first day as well.
In case you haven't been following, on the first day alone GTAIV raked in a hefty $310 million dollars (roughly). That is about twice as much as Halo 3's earnings on launch day which was about $170 million.
Congratulations Rockstar! Now the whole world can beat up hookers and mobsters in unison!
