Read this post, and come across my tale.
If amusement is what you seek, then read on friend
I will convince you by this tale's end.
Don't worry, I'm not actually writing you a poem.
Instead, I'm going to show you that you are morally obliged to share Dota 2 with me.
First point. As humans, we mainly seek to increase the pleasure of those around us, however, in this global economy it is very hard to know where the boundaries are for "those around us". Where does it stop? I would argue that after the advent of the internet, there are no boundaries. We are linked to all of humankind (or atleast those who have computers and internet, fuck the rest). In being linked, however distantly, we still strive to bring happiness and joy to others.
Now, this would be a good enough reason to give to just anybody, so why should you give one to me? I have never experienced the wonder that is Dota. I am a blank slate. I have none of the bad habits that you despise of players in the game. I can only improve your online gaming experience, so in a way, by giving it to me, you are also helping yourself.
Second point. I don't need a second point. That first one was gold.
