Actually, my claim is that buying a used game and downloading a pirated game have the exact same result: You play the game, the developer doesn't see a penny. This is irrefutable.

You can argue that people selling used games use that money to buy new games or whatever, but that's really besides the point (and has no statistical evidence to support), as I've demonstrated repeatedly throughout this debate.

And again, you failed to address my point: If you buy a used copy of Game A, Developer A sees no money from that sale. If you sell that copy, Developer A sees no money from that sale. If you use the money from that sale to buy a new copy of Game B, Developer A still sees no money.

You can keep ranting on about upstream cash flow but you really have no statistical evidence whatsoever to support that claim. And you keep referring to developers in the plural, as if they are all the same. No. Buying a new game from Developer B doesn't help Developer A. If you buy or sell a used game from Developer A, you are screwing Developer A. It doesn't matter if you buy a new game from Developer B. Different developers, different games. Is this really that difficult to understand?

I'm sure you'll jump on that example and point out how ridiculous it is but it effectively summarizes your entire argument. Just replace "pirates" with "buys used copy of".
