Not a humble bundle, but in the same vein, today I purchased the
Be Mine bundle. Games included are:
Wasteland Angel (PC Steam only)
Sideway New York (PC Steam only)
Xotic (PC Download + Steam)
Beep (PC/MAC download + PC Steam)
The Ball (PC download + Steam)
So you need steam to play them, they seem to retail for about £8ish each. I was a bit tight on this one and only gave them $5, as I have so many unplayed games already I'm not sure when/if I will ever play these.
