Straw paddler and sneaky editor-after-the-fact... you are doing sooo well in your argumentation.
As for the clips: Most of those enemies are crazed, zombie like cyber psychos, they had to bum rush Adam for story reasons... and the corp troopers at the start of the clip were armored and gave each other covering fire, they tried to smoke Adam out of his cover after he fooled them with his thermo optical camo... something that's not even possible in CP.
The CP clip, in comparison: Just an example of flashy, carnival shooting parlor gameplay, AI doesn't even matter in such scenario.
