Also, the third edition of the Humble Indie Bundle is going on right now. For those unfamiliar with this, 6 games are bundled together and you can have them all in exchange for a donation to charity (which can be as low as $0.01, though I know none of the Adventure Gamers forum users would stoop so low
). As a special incentive, if you donate at least the amount of the average donation (which is currently ~$5), you can also download all the games in the second edition of the bundle.
There are some great games in these bundles, including Machinarium, Braid, and VVVVVV.
So, I would have to say, ignore my previous post and buy Machinarium with a donation to charity.
