The last time Saints Row: The Third was in a pay-what-you-want bundle, its publisher went bankrupt in about a month. We're not saying--we're just saying--Deep Silver might want to watch it with this new four-or-more Steam game Humble Bundle.
Saints Row 2, Risen 2: Dark Waters, and Sacred 2 Gold join the probably-not-cursed open-world game for any price. But if you beat the average ($4.78 as of this writing) you also get Dead Island: Game of the Year edition, and all the DLC fixings for SR3.
Pay $25 or more and you can get Dead Island Riptide, too. Considering that the standalone expansion is $40 on Steam right now all by itself, that's a pretty good deal.
