regular mo:I'm completely perplexed as to how to access community content through my Xbox360. I can't believe that MS have done so many fantastic things in regards to growing its own indie dev community and then throw it all away by hiding the content through the XBox dashboard.
All content in the NXE (that isn't featured or advertised) is hard as heck to find now. It's not a problem solely with XBLCG. (Which, pedanticaly, it's XBLCG, not XBLAC).
I'm about 70 percent complete on my first full XBLAC game and I'm considering stopping development and porting it to the iPhone platform.
Then port to it. No need to come here and write that you're thinking about it; it's not going to change overnight. If you feel the iPhone is a better platform, then port your game and make your millions.
