> On the one hand paid upgrades can produce the wrong incentive on the developer The incentive to continue development? > ... Steam ... You can't compare traditional software to games. A game is finished at some point. There are only bug fixes to come. Traditional software is expected to get feature updates. If you want to see what happens when software gets to the "finished" status take a look at the outcry Sparrow created. They halted development of new features and people went crazy. As a developer I'm perfectly fine with no paid upgrades but then don't expect updates for your already bought software - you got what you paid for.
