Halo:
Pros:
- You actually get some changes in the game. (Forge, Theatre, armors).
- Huge plot.
- The little things (namely, being able to see your feet.)
Cons:
- Your Face isn't seen/doesn't speak much.
- The games don't show what happened between games (how many kids actually read First Strike, then didn't make a crazy theory on how Johnson got off Halo?)
- Crazy Fanboys
Modern Warfare:
- Made modern shooters popular.
- Easy to follow
- Intresting moments (Nuke, All Ghillied Up)
Cons:
- Swiss cheese/shotgun hole filled plot anyone (MW2)?
- Makes the SAS seem invincible/can take on the world.
- Your face is hardly seen at all (Ramirez, Allen, Roach) and you don't speak (Ramirez, Roach), even though you were pretty chatty throughout the rest of the game (Captain Soap).
- Apparently, masks+voice=character development (Ghost).
- UnknownMidEastCountryistan is not the same as Iraq/Afghanistan. Don't care if it was for political purposes (See WWII).
- Make two-three tiny changes max (WWII-Modern+Modern stuff)
Both
Pros:
- Provided some awesome memes (Ramirez, fight the Russian Army with this spoon while Dunn and I eat at BurgerTown!/I think Halo is a pretty cool guy. eH fights aliens and doesn't afraid of anything.)
- Excellent music.
Overall: Halo.
