User blog comment:Callofduty4/Why is it a sin for Treyarch to rip some aspects off of Infinity Ward but OK for Infinity Ward to rip off some stuff from Treyarch?/@comment-1664836-20091224020444

it's because IW is superior. it's because IW takes stuff and improves it. unlike treyarch. who take stuff and make it worse. compare COD2 to COD3. ugh.
