Sorting by games fer mei. Goodities first, badness second.
Hal good: Driving, driving people, gunning, blowing VEHICLES up with everything but the spartan laser and the mine, shooting people in the face mid-short-longish range ('assault' weapons only), laughing at everything and gasping when I'm doing good, assorted team tactics, using the gun that none use and is good with it, jumping with my reload finger and still aiming and moving with my thumbs while shooting, hiding behind places when I know enemies have seen me and are in hot persuit, then ambushing them, rushing in with good reflexes.
Bad: sniping with a lot of enemy cover, getting hit by grenades, throwing grenades that stick to people at the ground in front of them, throwing grenades that explode on the ground only directly at people, not harming them, blowing PEOPLE up, hitting my teammates with cars and debris.
CoD:
Good: choosing perks and unique weapons
Bad: everything else. Rushing in without good reflexes.
GoW: Tps=close enough.
Good: faceshot with longshot, hammerburst, shooting cowboys, kantus pistol, shield, special executions, for the horde (locust)
Bad: everything else (close quarters shotgunfaceshowdown) and COG
Strength in all: NPC killing. Anything to do with Melee attacks or weapons.
