What are you smoking? Modern Warfare not flying in space killing aliens.
Why specifically are aliens unrealistic?
Sure, they're not proven, but given the Drake Equation, in our Galaxy there are tens of thousands (my memory is sketchy, it is probably much higher) civilizations on other worlds.
Halo is more realistic as every otherwise 'unrealistic' aspect of it is essentially fixed by the fact that it's based in the future. Including higher health, (Absorbtion exo-skeleton energy shield, discharging it will make armor lock or a more direct release of it will make a jetpack).
Including destroying tanks with your fists (basically another discharge, however the sophisticated exo-skeleton, like that of the one in Crysis, is what powers the human so much).
Russia's a little ****stain on the world, they couldn't even hold onto Georgia!
I would argue against this, however I won't as it will benefit triggering an argument in a place in which it shouldn't be. Please doon't bring in politics.
Anyway - I haven't even played Halo Reach and I am sure it is better.
It introduced new, balanced mechanics and weapons.
It introduced a great new Forge which is very fluent in customization for people, allowing incredibly creativity to be made.
It introduced a fun aspect of the game (as it won't possibly go competitive due to its lack of dedicated servers, and in the end, a PC), where Spartans and Elites had significant changes:
Spartans for Utility and Fluidity
Elites for Brute Force and Juggarnaught Health
Anyway. I'm tired. See ya!
