Agreed.
Introversion managed to stay alive through selling their four games for $5 on Steam. That's ultimately not too much better than the current average bundle sale (http://forums.introversion.co.uk/introversion/viewtopic.php?...).
These deals tap into the reservoir of people who aren't invested enough in the games to pay full price (I forget the exact term for that), and these games certainly aren't new, and each has been on sale on Steam at least once so the people who were going to buy for full price likely already have.
If I have a great time with these games, I will probably double my payment next time. If I don't, I probably won't buy the next bundle at all. Either way, I can get my feet wet again with games with a low barrier-to-entry price.
Also, let's not forget that the cost of production of digital goods is essentially $0, and you could view this as an alternate channel for game developers to make some extra sales while getting people pumped about their future games.
Also, I wouldn't write off the next bundle if this one doesn't suit your fancy. In my opinion the games in this bundle are more casual than games in previous bundles (I wouldn't consider Aquaria, Revenge of the Titans, Penumbra, et al. to be all that casual anyway).
Not that you need to worry about the next bundle at this point X3
I'm speaking of the specific market of fence-sitters who may have pirated the games but in this case are willing to throw a couple bucks at the games. Those people who who you never would have gotten money from otherwise.
The people paying that amount could already own the games, they could already donate to charity. This is pay what you want for a reason, a large portion of people purchase just because it's a donation thing. If someone has a spare $5 why don't they spend it here? It isn't pathetic, it's better than nothing.
