this is what i understand out of it, and aoe2DE is not the first game which refused including blood and corpses in the game ( which was a part of the game in the previous versions of it ) after china’s government set new rules for video games in earlyISH 2019. you can read it here
i might be wrong and maybe they had other reasons for it, but when they are keep ignoring the people and not giving an explanation about it, then i cant think of something else
and you can see some examples of other games in this video:
