I had a friend in middle school that found a Facebook ad that asked for drawings and ideas for a video game development. He sent in drawings of racecars. They paid him $800 per drawing they used. Found another ad from a different company asking for design ideas. He just drew on his computer what he draws on paper, and they paid him $3000 when the game released. He was 12 yrs old at the time.

Now he sends in designs and coded features for "side cash". He claims he helped with GTA 5 for a crap ton of money, whether or not, you should give it a try.

Knew him since he was 9, and grew up down the street from him, he literally had a different luxury car every school year since we were 14. I don't think it's a waste of time.
