How can a kid create there own video game

you can buy game design packs and kits at the electronics department in walmart. Try a record tool, im using a pretty now - PCH and Screen Recorder.
it could record any activities on the screen and the audio whatever you hear, even the left and right mouse clicks and mouse highlights can be recorded to be displayed in your recordings. i think it is the perfect assistant to create demo video. what's more, it could record any audio and keep synchronous with video.
hope it could help u. http://www.screen-capture-record.com/screen-recorder.html
