Buy Broforce and play with me! For Freedom! :D
I haven't tried Mercenary Kings, but Broforce is awesome. It's not complete yet, but it gets content updates often. You can get it DRM-Free+Steam key from the Humble Store. It's cheaper than Steam, for whatever reason.

Hmmm.....1$ is awful. but BTA is quite good.
Also, there is DRM-FREE sale in Humble Store right now.

woah, just checked the humble store and they included a search filter for DRM!

It seems to me this is a BIG step ahead, not only helps drm-cautious gamers, but in my opinion raises awareness to all customers about the nature of their purchase. I always hoped it would appear someday as an option, I had even emailed them about it when Humble Store opened. Gog is still better though :)

Funny thing - week after week Weekly's deals offer less and less "valuable" games. For example its just little more 100$ this week. Some time agoit was 200-300$

I just finished it. It's decent, but there are a few really annoying issues. The Eurogamer Review reflects a lot of my thoughts. I can't recommend buying the bundle just for SoR, especially since the BTA is ~$6 at the moment.

On the bright side, 140 and Antichamber are great!

Oh, right, I totally forgot that the BTA price can rise ... I already have Antichamber and Cinders, what's so great about 140? And have you tried Ballpoint Universe? How long did it take you to complete Raetikon? In any case, thanks for the reply!

Raetikon only took me about 2-3 hours.

Basically, 140 is a platformer that uses music in an interesting way. Obstacles and platforms are synchronised to the music, so you'll have to time your movements to the beat. It's short(took me no more than an hour), but it's a very enjoyable experience. The controls are tight and I really liked the minimalistic artstyle.

I haven't tried Ballpoint. Edit: Gifted it to a friend

This is exactly same that i felt after reading some reviews. Too short, too unfinished.

As for BTA - it raised for 0.03 since yesterday. I dont thing it will grow any more significantly - everyone who wanted bundle got it already.

BTW, how is Cinders?

I own and it is GREAT! Art style, music, and character development rocks!! If you want to give a try, PM me and I can send you the drm-free for it.

I guess it depends, for example Edge of Space and Darkout are on my wishlist from some time, Signs of Life look promising, if I was not broke I would consider to pick that one. 1st tier is not that special as most of the games were in other bundles alrdy. From the bright side, most of them is DRM-Free. :)

There is the thing with free gog game and Curse Premium that Aniki mentioned too.

I picked up the bottom level - I'd been eyeing stacking and reign maker for a little while, so I tossed them $2.
