Well you can play Aikido without skill and you can play wushu without skill.
Both are luck based if you have no idea what you are doing. It depends on you. You are able to counter almost every opening move of your opponent if you play well in both modes. But you can also play them really lame.
The skill is just more viewable in wushu (e.g comebacks, dodging, etc). In Aikido you have to know how to deal with pushes, lifts, flipattempts, shifting your weight, (un)balancing.
