The first cod I ever played but I played COD4, MW2, WaW and even COD2 not long after and honestly enjoyed those all more. I didn't like the map designs so much, there was the whole problem with everyone using ghost because there was no stopping power perk as a trade-off, some stuff like sniper ADS and shotguns were stupidly nerfed, a lot of other guns were too statistically similar to each other like certain SMGs only existing to be identical to others but have smaller magazines to justify having an akimbo attachment.
