Yes, other companies manage to get games out for both at once, but most other companies don't sit on the same game for four years.
When did Microsoft officially become the publisher for Alan Wake? I'm pretty sure they weren't the publisher four years ago. Remember that Alan Wake was originally a PC exclusive or at the very least, PC was lead SKU. Observe: http://www.youtube.com/watch?v=4Fqb5VRtTL8.
Notice the lack of Microsoft. Like Halo, Fable, Gears of War and so many others, Alan Wake was a PC game that was turned into a 360 game because MS would have it no other way.
No other OS is even remotely challenging Windows on the gaming front. MS makes a lot more money off of games on XBox than they do on the PC. They don't get a paid by PC game developers like they do by XBox developers.
Truth. MS gets royalties from every 360 disc made. They also get royalties from DLC and downloadable games. They also get a steady revenue stream from Xbox Live (from both customers and advertisers). Let's not forget the overpriced peripherals either. Above all else, MS has absolute control over the Xbox platform. They decide what gets made, how it gets made and how much it sells for. They don't have even remotely as much control over the PC platform and don't stand to make nearly as much money with so little effort.
As I mentioned in an older thread, Microsoft has done more harm to PC gaming in the past 8 years than any other force.This comment was edited on Jul 7, 2009, 23:52.
