Apparently my last one wasn't "fair" (get off the weed) so I'm making a new one.

Killzone pros: Original storyline, good antagonist, war-torn environment, Helghast look awesome with thar red eyes, Killzone is quite challenging, 4 different characters to choose from with different abilities, Rico - Hakha relationship worked well (even though cliche), when you see Earth fleet get pwnt it looked awesome, pretty awesome melee, tons of geat guns to use, night vision.

Killzone cons: No character development really, no vehicles, no flashlight, bad AI, Rico's chaingun started with 999 ammo and 3 rockets -_-'', Jungle and Swamp levels sucked majorally, bad FPS, characters bodies wouldn't load properly sometimes, anti-climatic end.

Halo: Combat Evolved pros: Takes no real skill to play, no recoil, vehicles, Assault Rifle was awesome, (semi) original storyline, John is pretty bad-ass, co-op, flashlight, night-vision, great AI, fighting the flood was awesome,climatic end.

Halo: CE cons: Ghosts handled like ****, not a very good antagonist, very generic weapons, John looks a tad like a green powerranger.
