When a newbie asks a question on range it's generally in the vein of: How do I change weapons and drop them. Everyone answers on text or in short direct verbal comments. In each case information exchanged was about 6 to 15 seconds.
Six to 15 seconds has to do with short term memory retention and direct usability. A long film that covered the Help file in total would be as bad as forcing them to read the file.
1. - A Help file film collection of very short answers to the basic technical and game setup skills. At the end of the film tag in the offer to contact the Trainers, ask in the Forum, call HTC and so forth, like all well made help videos today.
How To: Map Keys
How To: Calibrate Stick
How To: Select gunsight and set convergence.
How To: Use offline target
How To: Setup and test VOX
How To: Setup Graphics
How To:....etc, etc, etc, and so forth.
2. - A Collection of specific videos for each ride(air,ground,sea) or manned guns. Charts are nice, show and tell is better.
If you want to make revenue from a demographic. You have to show them what they expect and are comfortable with. If their common help file is a video. Give them a video and stop punishing them with reading. You are driving away potential revenue because they won't feel like you are in business for them. The majority of new players should be able to get into the air and perform the basics in the first couple of game sessions with some offline work and the Help videos. After that, it's a small pond with big hungry sharks.
