Except review copies often don't have monetary value in themselves. They're usually prerelease copies which may not even represent final code (because reviews are intended to come out before release), are occasionally locked to specific networks (Xbox review code operates on a seperate network from Live, for instance), and some PC review copies simply deactivate when the launch rolls around.veloper said:Because even if something isn't considered a fun toy and just a boring tool, it may still have monetary value and even small favors deserve small favors in return. Reciprocity is a powerful thing.
Then there's the ad revenue, which is a big thing.
The only monetary value is in the work they allow the reviewer to produce, and that work is all done by the reviewer.
