I like both franchises but in its fairly short time compared to Star Wars Halo's lore is pretty deep and the races are stupidly power,plentiful and good at creating doomsday level weapons. I mean hell look at the Forerunners alone. Dreadnoughts capable of destroying planets on their own. The Didact's personal ship (mantles approach) is larger then the Death Star and is one of the smallest in size of dreadnought ships. (These are basically individual Death Stars and they had hundreds/thousands of these) Single attack crafts/war sphinxes these 12 meter tall craft have enough fire Power to vaporise cities and up turn continents causing enough damage to a planet to destroy all Life. (It takes a handful of star destroyers to wipe out a city let alone destroy enough of a planet surface to render it inhospitable) Onyx sentinels now these beggars have only been encountered as the first line of defence to shield world trevayln(I'm so sure I spelt that wrong) but they made up the entirety of the planets innards and number in the Trillions they combine and X each other's Fire power and shields a group of 50 is enough to take out a covenant carrier in one shot. Constraint fields a technology based version of the force basically making every forerunner a damn Jedi. Not enough well they held 3 million plus worlds some where for individual families but by and large the majority of those world held a high population number many having planetary wide shields over them. (Whereas SW going from the visual guides comics etc there's maybe a couple of thousand worlds names listed that hold a decent population or has been listed at all) Production speed these guys sure know how to build compared to the empire which takes roughly 1 year to complete a Death Star. Now compare that to the forerunners ability to strip down an earth size planet to it innermost core in 9 days and create a Halo out of those materials. Ships such as a dreadnought class vessel takes a couple days and single fighters take minutes onyx sentinels take 6 seconds. Also add to all that, that the force doesn't work on extragalactic life (Yuzan Vong) the Jedi and sith become nothing more then excellent saber fighters. Now imagine that ancient humanity and san'shyum where on the same technology level as the forerunners in all areas bar slipspace travel and you now have 3 extremely fast producing technologically advanced races that number in the trillions without even bringing in the Precursors. Each one of these races has Galaxy ending weapons while star wars Also has these level of weapons they are much more scarce then the ones Halo has.
