I think the original Halo had....5 weapons total for UNSC. Assault rifle, pistol, shotgun, rocket launcher, and sniper rifle. There were.....3-4 weapons for the covenant. Plasma rifle, plasma pistol, needler, and I can't remember if there is a forth. That's only 8-9 weapons. There are 25 different weapons in Halo Reach. Even with all that, the first Halo is still my favorite. Maybe it's because that's the original Halo, but it also had graphics and gameplay that was FAR ahead of it's time.
