The Warhammer 40,000 Imperium of Man would annihilate all others: an inexhaustible army of soldiers, tanks and aircraft supplemented by the greatest logistical war machine in existence, fusion weapons that can crack planets, virus bombs that can decimate worlds, walking war machines the size of skyscrapers that can devastate cities, starships the size of continents, and of course the Space Marines- superhuman warriors that dont need sleep or food, can crush skulls with their bare hands, are bulletproof and can spit acid - oh and they wear solid adamantium plate and their standard firearm fires depleted uranium slugs that explode inside their targets.

No Halo fanboy can tell me the Forerunners could stand against that.
