Halo's campaign missions you start with a set of weapons, and have to find weapons throughout. Destiny, you have whatever weapons you want when you want. Halo's story is MUCH better. No grinding to unlock guns in Halo. No sprint/non-scope ADS in Halo Different grenade mechanics No "super-melee" in Halo No classes in Halo No armor abilities in Destiny Etc. The two games have a lot in common, but a lot of differences, as well, that you could like one and not the other is easily understandable. I personally like both, but I think Halo's a bit better. (and understandably so, since it's 6+ games in)
