I've played about 4500 games (on different accounts)
My first account - @Collestar
It has 3600 games. + A few more closed accounts with about 500 parties. It turns out even more than 4500 games. I think that I have definitely played about 5500 games (from all accounts, including those closed)
458 till date
I'm not sure but I think it's more than one hundred thousands.
