I don't know what game fancier is, but I do know that there are several Americans who love doing things on the computer like playing games. Another really big online service is Facebook.

I understand that online translators are bad and that they are 95% incorrect. You should only use online dictionaries for vocabulary. I understand that grammar can be difficult for you, as Chinese is not a grammatical language. So for now, know this; "There is" is for a singular noun. "There are" is for pluraly nouns, like people. Indulge is not the right word here. You want to say, "Are there a lot of people who like computer games or just really like to be on the computer?" Don't worry, I have trouble with Chinese translations, too. The two languages are very different, and so you just need to keep practicing.

Eliot，Can you tell me how should I express?

I don't think it's by google. The game is called "fancier"? Sounds like a very fancy game.

Please stop using Google translate. It sounds terrible.
