I am both a pc player and a console player, so i think i can throw opinion in this Drwalter you are very good. if you took someone with equal skill to you, but in pc i think he could do better just for the fact that they have more control than well with a controller, but im pretty sure it would never happen like that so theres no reason to argue it. because its just the same fight thats been going on for a very long times pc players v. console players.
also 15 minutes sorry thats not going to happen it would take months- possibly years to get that good because halo is very different than any other game in my opinion.
