So you can choose what to pay for huh. That's...kind of weird.
There have been a few instances of the pay-what-you-want model, including albums from Radiohead and NIN, as well as the Humble Indie Bundles of popular indie games. It's just another way to combat piracy and still make a little money... pirates often cite "too expensive" as a reason to steal stuff, so this sort of removes that excuse. People who think $20 is too expensive could chip in $5, or at least $1. Or really at least $0 I guess, if you think that's all that it's worth to you.
[quote:ioks2yb8]Does this mean people can charge for plugins?
Yep. If they want to. But plugin creation in C2 is going to be a whole lot easier than in C1 so it better be a really good plugin or someone is likely to make one that does the same thing for free.
