I feel kind of like a jerk for always wanting to buy these at minimum or close to minimum amount of money. I mean, I have a mild interesting in playing two or three of them, but never enough to pay steam-sale price for them, so I never end up buying them. Essentially, if I don't pay a small amount for them in the bundle, I'll probably never end up buying any of them. So I guess it would be fair, since it's "pay what you think they're worth". But it feels like the unstated idea of the whole thing is to come together as a community and show that we're not pirates and that if given the chance to take something for (practically) free, we'll rather pay full price for it. And paying a minimum amount for it totally feels like not getting that point :-/
I don't know, maybe this time I'll buy it anyway, in spite of my better conscience...
