First thing's first - I'm loving the bundles as they have been for the last three times - THQ, Deepsilver, and an Origin bundle? You're losing money if you don't buy them!
That being said, I feel like the Humble Bundle (run by Wolfire Games, the Lugaru/Overgrowth/Receiver dude[s]) is losing its focus, or at least the focus it had at its genesis. It started with some indie darlings (I'll not list them off - go look up the wiki page for it if you care), some bigger than others. Along with the weekly sale, there have been plenty games I haven't played or encountered before. However, now that they're the biggest bundle site in town, they have set their sights hell of a lot higher. THQ was going down the tubes and Deepsilver ain't that big of a name; I do wonder how they roped in EA to offer so many damn games for so little (snagged them for 10 bucks myself). I guess there's not much to complain really - people get games and charities get donations, but it does seem to defeat the purpose of having "Humble" in the title when you're offering the biggest AAA games from years past.
I am aware that there are plenty of smaller bundle sites out there, and they deal with hella obscure games that I haven't even heard a peep about, but as a 99%-er (or whatever you'd call it), I like to root for the small guys and seem them get theirs, which was definitely happening in the beginning - now, not so much.
Am I just a hipster douchebag who whines when too many people are enjoying the thing I was enjoying 'before it was cool', or does my criticism have merit?
