Where can you host?
Anywhere you want! Homes, pubs, company events, after school programs, exotic beach resorts, yacht parties, weddings, wakes, you name it. (OK, probably not wakes, but you get the idea)
Can I pick what games you bring?
Of course! If you have any specific titles in mind, or that you are particularly curious about, those will be given preference.
Is this intended for a specific age?
Nope! There is a game for everybody. And while the age of the group may effect what is appropriate to select, I can find the right game for any age.
Will g2t join in playing the games?
That is totally dependent on the size of your group, the games being played, and your preference. For example, larger groups may benefit from someone moving between the gamers to help learn rules and facilitate play, while smaller groups getting the feel for a heavier game might benefit from an experienced player joining them for the duration.
