All Points Bulletin was originally created by the creators of the GTA series, but was shut down only 1 month after its release, most likely due to the fact that they released the game in Beta. Back then you had to buy the game and pay an additional monthly fee, so naturally people didn't want to blow their money on an unfinished game, causing the company to go bankrupt. I actually played the game back then and it had about 60% of the features it now has in the Reloaded version, so it didn't surprise me that alot of people couldn't be arsed to play it.
However, after a while the game was bought up by K2 companies, also known as Gamersfirst (For an amazing £1.5 million) They then decided to continue development on the game, allowing beta testers and preparing for release. After about a month of playing as a beta tester I sorta forgot about the game up until the release of APB: Reloaded (18.05.11) which is the "final" release of the game. APB is now free to play and waaay better than it was before, so download it and give it a go!
PS: Stunting is good there too.
