Yes, I want more games, but even more so, I want annotated games.  One of the
best (and largely ignored), extra features of the Fritz5 games database is that
around 5000 of the games are annotated.  And a lot of them by text, and theme
keys.  They come (I'm pretty sure of this), directly out of previous editions of
Chess Base Magazine, which is another of the growing list of products from Chess
Base, that can be recommended without hesistation.

So if they upped the number of games to non-CBM subscriber's, they would be
doing Fritz5 upgraders right.

And no, I do not work for Chess Base, though if they offered me money or
products to recommend their stuff, I would take with pleasure:)
