Combat Arms was great in Open Beta. It was amazing.
I stopped playing as soon as it left the Beta stage assuming hackers would fill the game, and a cash system would cause severe balancing issues.
I was entirely correct. Combat Arms is now a pile of pure garbage.
I'm not trying to be tribal here, but Koreans don't seem to know what makes a game enjoyable. The most decent thing I've seen Korean was War Rock; before the L85, M82, Scorpion and all those other stuffty new weapons came out that you can only get through real money.
...And that's because the game was optimized well, and had solid gameplay that was generally copied from Battlefield, a game I had only heard about back then.
