If you have used Steam (the gaming platform) you know that it considers you are playing a video game (the software application is running) from the moment you push the green play button. Even if you don't go past the intro screen for hours or spend days running in a loop on the first map the app still considers you are playing the respective video game.
I have played multiple times, some to completion, some just a level, a lot of the video games that I bought and I OWN. Just like I own the automobile that I once bought, just once I bought it, not multiple times, and when I bought the vehicle it legally passed into MY possession. Now I can play with my car MULTIPLE times, whenever I want, not when the car maker allows me and the same car maker doesn't charge me money each time I open the door of my car or I start its engine or drive 100 km.
Keeping to the car analogy, instead of paying once to own a $50,000-$100,000 AAA car, you would prefer to pay $1000/month or $100/day of usage of that respective car, and I think I've been generous with those percentages, not like the prices coming from Ubisoft & Friends.
Blink 182 times if it computes.
