I actually did track the number of games that I played, ever since I bought my first DK cabinet. It was an exercise in tracking my investment, to see if I'd "get my money's worth" for the cabinet, if I imagined that each game I played cost a quarter.
Initially, I was playing like most players do: trying to advance past as many stages as possible. I progressed from scores around 100k to 400k.
Over time, I progressed into more advanced DK strategy, passed the half a million mark, and eventually got into the 700s.
By that point, my strategy for playing had changed significantly, and was no longer "running boards" to get a higher score. I found myself restarting games a lot. Consequently, it was difficult for me to keep track of the number of "real games" that I'd played.
What I mean is, if I'm restarting constantly, in an effort to get a good 1-1 and 1-2, do those restarts count as a game? For my initial thinking of "one quarter per play," I think that it would... but now, after a few years of owning my DK machine, I don't consider those restarts to be "real games" anymore.
Currently, I aim for one good game a night. It might take me 45 minutes to get a game going, and some nights I won't get a game started at all. So when I read "203 games" in this thread, I question what that really means. 203 days? Or 203 quarter drops?
