Many blogs have already reported about the Humble Indie Bundle. So just a short notice: Download 6 games for Windows, Linux and Mac and pay as much as you want.
Wait: 6 games? The other blogs all said they are 5.
Amnita Design (The developers of the really nice game Machinarium) have contributed Samorost 2 as well. I have not yet played it, but I am sure, i will.
The whole thing is running for two more days. So pick your wallet and pay whatever you want for 6 games.
