APB is awesome ("is", not "was", since the servers are still up, it's free to play for anyone who has an account etc, but no one knows for how long). After they added recoil, new sound effects and a vastly improved matchmaking system, it was pretty much what it should have been at launch. It's a shame for such an ambitious project to go to waste... It had a lot of potential but, due to a few fatal mistakes, failed to show it off to the world. Reminds me of my fav game of all time - PlanetSide...
And, like with PlanetSide, APB's failure will make sure that no one will ever try to make a similar game ever again. Only WoW clones, cause any pencil pusher type decision-maker can see that APB failed and WoW is a great hit and money factory... :P
