I usually play on my desktop computer because it runs more faster and smoother and I usually use my laptop and macbook for school purposes.
And yes, I know that you can just simply plug in a HDMI cable from the laptop to the TV but I'm pretty sure that not everybody has a HDMI cable lmao.
Other than that, if we are able to make the game re-sizeable, it would make PKing more easier because we have a better vision on what we're doing and don't have to squint our eyes on the monitor or get up close to the monitor lol.
