Rumour is beginning to circulate about a plan Microsoft was hoping to keep quiet in making Windows Phone 7 more appealing for mobile gamers. Word's gotten out that Microsoft wants to make the new platform successful not only in terms of its general user environment, but also from a gaming perspective and is going so far as to entice iPhone game developers to produce Windows Phone 7 ports for them with $$$ being waved in the air.
Whilst this could very much be a win win situation for both parties when looking at revenue potential, the issue is that WP7's underlying development environment is substantially different from that of the iPhone's, making the porting process a lot more involved than one would first think.
But, money talks, and perhaps if enough of it gets waved around then Microsoft will be offering a terrific catalog of apps straight out the gate. Heaven knows they have the biccies to make it happen if they're dead set.
