Your analogy is a poor one.

1. “you” as an independent developer don’t have a vested interest in selling apple hardware. Microsoft and Sony do.

2. “you” as an independent developer don’t have the resources to fairly easily port an app to another platform, like Microsoft/Sony would.

3. Market saturation for apps is not really comparable to AAA games.

4. I don’t think piracy is a big concern in console games, but maybe I’m wrong. I don’t keep up with it.

To me, the only reason Sony is doing it with their back catalog is to try to generate new users for their upcoming sequels. The game is at the end of its earning lifespan if they don’t port it, so why not use it to market the upcoming titles?

So you’re saying releasing games on other platforms is beneficial for game sales?
