Was playing with a few friends and we were all on Mars, bending corners on our Sparrows. Then I thought, "If they (Bungie) made a racing mode when the expansion ships, they can take all my money now." Imagine like a Star wars-type map where you'd be racing through a forest, weaving through the trees, over and under fallen logs, dodging incoming fire from the dude in second place. Just different enough to where it's still Destiny. Just a thought :P
