Steam Play Indie Pack

Someone is shining loving, caring light on the frugal gamer. Through Steam, which has often been known for siphoning money from my bank account in the name of excellent deals, there is now a Steam Play Indie Pack.
Pardon me while I go back and look at a few posts of mine in the past two weeks.
Oh right, there was that other pack, the Humble Indie one. The one that raised quite a bit of money?
Well, if you still don't own World of Goo (considering how many times it has been pay-what-you-want...), you can grab it in this pack with And Yet It Moves, Galcon Fusion, Machinarium, and Osmos. In fact, if you missed the Indie Game Love Bundle earlier this year, this would also be an excellent choice, as three of those games are featured again here.
For all you Mac users out there, this is also for you. With the new Mac support, both PCs and Macs can get their indie-love on for the price of $19.99. As Steam's own page kindly reminds us, you end up saving $49.96, as the games all individually priced would come to $69.95. The sale lasts until May 19, so you have a bit to decide.
At this point I suppose the question should be raised what other indie games people want to start seeing in packs. For those of us constantly jumping on these sales, there seems to be less and less incentive to actually buy the packs whereby we already own the majority of the games through another bundled sale. On the other hand, with the recent addition of Mac support for Steam, this makes perfect sense for that platform. Hook them early, and all that.
So, readers, what other indie games do you feel are worthy of note and we should start see being pushed more?








Games I would like to see in the next indie pack(s):
Saira, Dangerous High School Girls in Trouble, Blueberry Garden, Zeno Clash, AaaaaAAaaaAAAaaAAAAaAAAAA!!!, The Misadventures of P.B. Winterbottom, Fatale, The Path, Eufloria, and Cogs.
I love World of Goo, but I already have three copies of that game now. No more Goo!
