Massively

When's the perfect time to launch your brand new virtual world? The one that will send kids hunting through their parent's wallets for money for new outfits for their virtual puppy. The one that will have people busily importing their five thousand-strong MySpace friends list into your Scooby-Doo-themed social networking site, The Haunted Amusement Park. Your Shiny Whiter Teeth virtual world that will launch aside your new toothpaste. It all depends on your target audience, says Electric Sheep's Giff Constable.

If you're going after the coveted pre-teen dollar, best to launch it just as the kids are getting out of school. Their parents will likely have their guard down and be more permissive. Though that won't work with college kids. Get them just after exams, but before the new semester. They'll be playing and getting their friends to play so when the new semester starts, your foot is in the door.

Adults aren't likely to play during the Summer (when their kids are hogging the computer, no doubt) -- grab them in the Spring or the Fall when the pressure of summer or the holiday season aren't on their minds. But if you're tying your virtual world to a toy or other consumer item, then the holiday season is your strong season, and you should launch in the Fall in order to make a big splash.

You can spend all the time you need on your virtual world, polish it to a high sheen, but if your intended audience is off doing something else ... you won't have the launch you want.
