I remember back when I played the first Halo an remembered that the biggest reason why I wasn't too hyped up on it was because the weapons selection was small and not as innovative. I thought Halo 4 did a great job on adding more creative weapons and would love to see Destiny take its weapon selection to great heights. I mean look at Turok 2: Seeds of Evil; old game, but great creativity, look at Ghost Recon: Advanced Warfighter, the selection is huge an look at Deadspace 3, the customization. Their is so much inspiration in all of the above so I think it would be great to see some clever weapons.
P.S. I really want a futuristic bow an arrow set up, mainly so I can see arrows sticking out of my victims, no gamer can say it's not dope to see that, especially when it's a shot to the face!!!! :D
