No two games alike?

I'm sure you see your fair share of quick mates... at the higher levels there may be matches too (some opening lines have been studied all the way to a draw).
Hard to say... there would be some, but not many I'm sure.

eternal21, at the master level, players are familiar with the games that came before. Wins and losses are rarely the same, because the losing side tries to make improvements. But games where both players are content with a draw are often identical. For example, the 11-move draw 1.d4 d5 2.c4 c6 3.cxd5 cxd5 4.Nc3 Nf6 5.Nf3 Nc6 6.Bf4 Bf5 7.e3 e6 8.Bd3 Bxd3 9.Qxd3 Bd6 10.Bxd6 Qxd6 11.O-O 1/2-1/2 has been played 386 times.

The draw game mentioned above:
1.d4 d5 2.c4 c6 3.cxd5 cxd5 4.Nc3 Nf6 5.Nf3 Nc6 6.Bf4 Bf5 7.e3 e6 8.Bd3 Bxd3 9.Qxd3 Bd6 10.Bxd6 Qxd6 11.O-O

I wonder how often do we end up with identical games. For example, there must be thousands of games being completed daily on Chess.com. How many completed games are identical, move for move? I guess this is more of a question to somebody in charge of the database...
