How come the original Xbox had no RPG games and the Xbox 360 now has a bunch of RPG games?

I microsoft trying to steal away Sony customers. Xbox now even has games like Final fantasy tactics. The original Xbox just had Fable, which was the closest thing to an RPG, but now the Xbox 360 has turn based RPG's.|||The system has been much more successful than PS3 so it's getting much more support from developers.|||They realised that rpg games sell well?|||Because the orional Xbox licks ***.|||more opportunity and better technology, there are games out there like world of warcraft and guild wars that are just packed full of things, and alot of detail





the original xbox wouldnt be able to handle that, and i will admit fable 1 was a bit annoying how you had to load each area, it wasn't just an open world.





but xbox 360 has amazing technology and is able to perform well and run games like that with amazing attention to detail and great gameplay.
