Not free, just free download & games?
I wasn't going to reply since this post was so old, but since it's still a google result, and I was searching for the same thing 2 years later, I guess it's still relevant.
I was looking for the same thing (my pc has lots of free games preinstalled. Sorry I'm not up to the caliber of the sole free game - Chess, which came with my Macbook pro. I googled and got the same results, above. The download is free (sure, who would charge you for a game & for the download?), but the game itself is a trial version for $14.95. The "buy the game" screen which plants itself in the middle of the screen has no closing option, though it is possible to play a game. More than one game, I can't tell. The game opens to the simplest version of spider solitaire without an option of choosing difficulty level. I deleted the whole thing.
As a new mac user I'm wondering what's the story on the lack of free games? Are we not worthy? Many yahoo games can't be played on a mac, even when using a pc-friendly browser like Firefox. I'm wondering whether I can buy a game on iTunes, add it to applications and play it on the powerbook without having to open iTunes?
