Are there any (free) games databases out there? I am searching for a broad and extensive games database (i.e. games played between real players.)

I can hardly seem to find any (even paid ones.) - However all sorts of chess software has these built in.

Where can I get my hands on one?

I will use it for a lot of analyses on different players, openings etc.

Hope someone can help me out!
There is a pretty big one if you are willing to spend some 40 euro.

This (Million Base 2.2) is the biggest free database I know of.
