You may have seen some of the Astros celebrating with a dance from the video game "Fortnite." The free-to-play game is dominating the game world -- but some worry it may be inappropriate for little kids.
"You play online; even though you're sitting in your living room, you play online with a team -- people you don't know physically -- from around the world."
Garfield says it's a game where you build forts and it looks like a cartoon.
"The graphics, although very sharp, it's rendered very cartoonish; everybody has an avatar and you can dress yourself up in different characters, like a pink bunny suit."
Garfield says those graphics are a double-edged sword; they're not very realistic, but their cartoon appearance entices little kids to play.
"It is up to parents; as a parent I have three boys and I have always been cognizant of what they're playing. I try to play the game and make sure they know it's a video game and not the real world."
Garfield says Fortnite mixes fort building with murder and cartoonish graphics that appeal to kids.
