Such a pity for the workers at Realtime - I'm sure that some of them have talent which could be used to make a great game. Unfortunately, APB was not a good game.
MMO's are risky. Frankly, I think this was doomed from the start. First of all, what draw was there for people to go to APB? Unlike a Star-wars MMO or a Blizzard-game Based MMO, or a Star-trek MMO, there was no background to APB that would entice customers. If you are going to make an MMO, you better make DAMN SURE that there's a consumer base that is likely to be attracted to your product. As far as I can tell, APB did not have that base.
Yes, there's plenty of people that like GTA. But APB is not based on GTA, and has nothing to do with GTA except guns and cars, and both those elements are available in many non-MMO games.
Second of all, where was marketing? I use the internet a LOT, but I only heard about this game when people started posting reviews. I doubt many people even heard that the game existed until it was released.
If you don't market your game, how on earth will it sell? And an MMO MUST SELL. If it doesn't sell quickly, in big numbers, if it doesn't gain that critical mass quickly enough, then the few people that bought it will desert it after they realize that no-one else is picking it up.
Frankly, I think it's a bit silly for any company to enter the MMO market right now. I'm not saying that WoW is invincible or that Blizzard can't be beat (they clearly can, Blizzard is just a company after all, not a god), but that if you aren't willing to put a serious effort into it, you're done for.
For an MMO to succeed, you have to market it to all hell, for years, you have to put your face and your companies name in the media constantly, you need to get the hype factor rolling and you need to give people a reason to play.
If you are going to beat WoW, first of all, your game must be better and bigger than WoW, both mechanically, graphically and in terms of content. You aren't going to beat WoW any other way. You can't release a minnow and expect it to challenge a shark.
Although I feel sorry for the folks at RealTime, this project was always likely to fail, and their boss should have realized that.
