in the beta, we could buy new ships from the hanger. does this mean that we get a space mechanic that lets us shoot down Fallen fleets or have pvp space ship matches? if it does, bungie, YOU HAVE NO IDEA HOW MUCH MONEY AND POPULARITY THIS WOULD GIVE YOU!
The first game is confirmed boots on ground. However we can totally speculate on sequels. I mean, how well did space combat work in Reach? Very well. However, Destiny's strength lies in the creative use of powers, inapplicable to spaceship combat.
