Starting to make videos for our games. It's quite fun but also a lot to learn.Those nice AppPreviews are really attractive. But to put everything within 30 seconds and at the same time make it appealing is not an easy job. So what do you guys think of AppPreviews/Gameplay videos? How much does a game video matter to you, as a developer/player? Is there any videos that once turned down your interest? Which genres of games do you think is better to be attached with a video?
