Pretty good deal for a bunch of games. Pay what you want for them but if you pay above average (about $6) you get Saints Row: The Third as well. You can also chose if your money goes to charity or to the game makers, or you can do a split between the two.
I have all four Android bundles, plus the last three PC game bundles. Great value!
I've often thought about getting one, but never actually did it. Are they really that good?
edit - Oh it's a THQ bundle, I like the look of the indie ones better, they tend to work well with linux.
not exactly humble when its THQ lol
