I wouldn't know, I just open the game directly from the files. Probably a couple hundred since I only got the game ~6 months ago, but I play it a lot.
I have 440 hours logged in the game but before that before Steam I think I have got closer to about....maybe 800 hours max on the game but I am probably the lowest here
1471 since when the Mirimar released. Most of it is from me just leaving it running when i'm at school or whatever
