I'm not going to be buying it, because I already have most of the games on it, but the current
Humble Indie Bundle is a pretty good one.
Games I have personally played and can recommend:
Sir, You Are Being HuntedThe Deponia series (though I haven't actually played the last game in the series yet, myself, the first two are pretty solid)
Skullgirls (including all DLC)
Planetary Annihilation (I backed this one on Kickstarter. Also included in the bundle is a 66% off coupon [on the Humble Store] for
Planetary Annihilation: TITANS, which is basically the same game but with more stuff. Seems... a bit odd to me that they're putting a coupon in the Bundle, rather than the actual game itself, and I'm not sure that's a good precedent to be setting there, but... whatever... that's the only bad thing I see about this particular bundle)
Gone Home (despite what you might hear from most of the rest of the Internet, particularly the
misogynistic GamerGate assholes, this is actually a pretty cool game)
