World of Tanks… That game cost me several keyboards over the years. Even though its mostly a great game, the way RNG is integrated with the skill based game play can cause you to lose when you have done EVERYTHING right. I’m not talking with being matched with a team of elbow lickers, I’m taking about when you have caught an enemy by surprised, aimed for the right spot, your gun is more than a match for their armor, and ‘ting’ bounce… then they turn around and ammo rack you.
