Over the past 6+ years I've fought nearly 60,000 battles in World of Tanks. At an average of maybe 6 minutes per battle, that's 360,000 minutes, or 6,000 hours, or 250 full days worth of time played... and that doesn't include time on the forums, time doing management and garage-keeping tasks, time playing the little extra games they throw out from time to time like Chaffee racing or T-62 soccer or 8-bit Karl...
still, for all it's faults I love the game... still reminds me of playing with Airfix 1/72 scale tank models in the park with friends when I was a kid...
