I wonder why BeMine 2 isn't more popular. Haven't played the games yet because I'm busy with other stuff but this seems like a good bundle even if you don't pay enough to get Killing Floor.
it's in general a hard bundle to recommend to people for the following reasons.
A. their first bundle was botched horribly and failed to launch 3 times.
B. They do not send out a confirmation email of your order.
C. people have had keys missing or other issues but they usually fix them fairly quickly.
D. The site as a whole feels less professional than the humble bundle.
Personally I like the bundle, but when a launch causes a number of issues for some people it's hard to get those people to come back, and they tell their friends to not get it as well.
