mw2 was a better game for gamebattles
blackops is a better game for pubs
cod4 was a better game for pioneering the design
waw wasn't that good
cod 4+5 has terrible hit detection; you had to aim in front of them. Great map design, fair gameplay. Great gameplay minus hit detection.
cod6+7 have good hit detection, better hosting abilities and appeal to the general public, not focusing on skilled play, but fun, therefore there is a lot of crap in mw2. Blackops, treyarc listened to the public and did EVERYTHING they complained about in mw2 and fixed it to the point where they wen't too far and didn't look at what they were doing.
Every game has had glitches, fun to take advantage of, cool spots, glitches. Except blackops. Yeah there was the carepackage glitch already, for 3 days. Its the fun glitches I miss such as the never ending games of mw2, rust domination. Soo much fun and harmless.
