Release of lite version

For those who released lite versions of their games did you find it better to release the lite version and the paid version at the same time or release one before the other?

Well, I dont have any game-releases yet, but have had a couple of educational apps on itunes for a year, and I cant really conclude much more than the fact that sales pick up only when you release the lite-version.

Also, considering the limited span of attention your app will get, you NEVER release a lite-version first. If there is no immediate link to the full version from the lite, it will get uninstalled and forgotten, and most likely never downloaded again.

Ideally, you want the full version first.

Especially if there’s a high likelihood of the app not being opened a second or third time (ie, with a lot of people you get one chance).

There have been a few apps that have only had a Lite version for some time before the full version was released and they’ve done quite well for themselves.
