By narrowing down the type of game, the operating system and the year basically.
I know pretty much 80-90% of the games in the DB so I looked for games I didn't know with a simple name (like Qix, Kix, Styx, Xonix). I still had to go through 30 games or so :P
But whenever someone posts a game I don't know, I just really have to know what it is.
Hmm you never specified if it was a $5,99 or $9,99 game so:
Baldur's Gate 1
Tex Murphy 1+2
A little bit of choice so I can still be surprised :P
smannesman a-t yahoo.com should work.
