Tried KOS from dontblynk? that's a fun one, also try google or anything. I have a shitty pc aswell, so I know what you're going trough.. Try League of legends aswell. Even though the gameplay trailers might not amuse you, it's still worth the shot. Good luck.
This is not China where filthy douchebags make young children work 18 hours a day per one empty slice of bread.
You don't have to work a lot? I do misc. odd jobs and IT for my dads work. (like a consultant) It gets me what I want and I am 16.
Hardly 18 hours a day also until you are 18 most states limit your week to 40 hours max.
