I barely play any mobile games...well other than Angry Birds. I had really expected Aerospace to be somewhere along the lines of Space Exploration not mobile games. Mobile games are something to pass the time but I'm sure Bungie has their own reasons. Perhaps Halo 4 will be the last of the great games of the Bungie universe. Maybe they needed a new challenger to step up and surpass Halo? Im still looking forward to Halo 4 and Halo Anniversary anway!
