APB: Reloaded has become a victim of its own success and that's not necessarily a bad thing.

While some issues have risen from the massive influx of players since the APB's open beta began last week, Reloaded Productions is stepping up its game to get APB: Reloaded whipped into shape. Last week the game shattered its peak concurrent users record with just under 24,000 players all logged in at once. I'll let this quote from the blog put that into perspective.

To put that in some perspective with some of the great games out there (some F2P, some subscription); Eve Online announced back in 2007 that they had reached 35,000 peak CCU, which was 4 years after the game was released. World of Tanks announced in April this year that their PCCU reached 25,000 after a year of Beta testing. Nexon announced that Combat Arms beta had reached 12,000 PCCU in Europe in their open beta running for 10 months from December 2008 to September 2009.

This is good since the game is proving to be quite popular, but this volume of players can lead to some spacing issues. As such, some free players find themselves waiting in a server queue at certain times. If you're a premium player, you'll get to cut in line a bit since you're helping to support the game. But queuing issues should be worked out before the game's official launch, or at the very least trimmed down significantly.
