Is it hard to get an online game going?

When g+ was new, I remember how some people hailed it as the future of gamers lacking a group. Now all the online community was open for recruitment. That sounded so good I dived in.

Since then I have tried multiple times to sign up to people wanting to run games, and never has there been anywhere near a full group showing up. Mostly it's just me. Still, since I am stubborn I'm thinking of buying a headset and a web cam and try my luck at recruiting some players of my own. That Delving Deeper game has got to me!

But how do you do it? Have someone written a tutorial to how to set up a g+ event and how to run a hangout game? If anyone reading this has a clue, feel free to enlighten me.
