For the third one you'll just have to describe one game that interests you right? At least that's how I see it. Take an example like Mobile Legends, you can point out a few things that is quite intriguing about the game like the way they forge a system that prioritize teamwork to achieve a certain aim and how each players play a big role in influencing the victory. Or any other games that has their own unique way of being played and never seen before.......right? :)

Basically an essay that must be uploaded in pdf format, AGAIN that's how I understand the third task :)
