Why did I get 'Nobel Prize' with unplayed games?

[Stuff by Bez]

I got the 'nobel prize' achievement and though I'd been working towards it, it feels a bit sad that I still have 79 unplayed games....

Some are in beta, but most aren't. Most are games I've started (but not finished) a turn based game of, but 2 games I'm still waiting for folk to join and 3 games (that are realtime only) I still haven't played.

So I was wondering why I got the achievement, and how exactly it's calculated.

Most likely, you get the award when your number of played games (including alpha and beta) equals the number of released (not alpha or beta) games.
