Groupees has been running its Build a Greenlight bundle for a while now. Originally offering (up to) nine distinct games, this digital package has since grown to include a number of free bonuses, like La-Mulana (the remake) and its original soundtrack, a holiday chiptune album, and more.
At the very least, Groupees requires selecting two of the core games -- most of which you likely aren't familiar with already -- to build your personal bundle. The minimum for that is $1.50, an absolutely crazy price considering La-Mulana is being thrown in at no additional cost. The more titles you add to your purchase, the higher that minimum becomes.
As the name would imply, the point is to raise awareness for the featured games on Steam Greenlight; even if you aren't interested in buying this stuff, take a minute to upvote any games that seem worthy of seeing full release on Steam.
