Make sure the game you want to record is allowed to be posted online the best place to check is from the makers of the game itself or go to http://www.markeedragon.net and type the name of the game you want to record and with some games you can earn some money with the youtube partnership program.

As for recording the game make sure you have a good game capture device if your recording from an xbox, playstation etc also if you are using the game capture device to record games you'll need one HDMI screen to play the game and one computer monitor for your computer to record the game as there is a delay when recording so when you press a button on your controller it will take a few seconds to record the action you have taken.

Make sure your computer is good and can handle the game footage and webcam recording together and get a microphone to record the audio as the audio from webcams usually isn't that good and can have a lot of static and if you can't use a webcam then that's ok some gameplay footage is gameplay plus commentary on the microphone.

Where do you intend to upload the content? Do you intend to upload it onto youtube or are you planning a live streaming session on twitch or another online service either way it's a good idea to also have a website with ads, products but whatever you do don't promote a separate product such as a book or tshirts etc within the video recordings as game makers will ban your video. The best thing to do is create the gameplay add a link within the description to your website and make money from the youtube partnership program, ads and products on your website not on the video but your website.

Also look at patreon in order to make some money from your video's as well

You’d better not use the camera to record a gameplay video, if you don’t want to get a poor quality video. The first thing you should do is to choose a screen recorder application suits you best. Some screen recorders are free and some needs you to pay. Once you got a favorite application, you should customize recording settings based on your preference. BTW, remember to select audio input source. More tips could be read at this guide about gameplay recording.

One of the programs I used to record game footage from the computer is OBS. It's pretty dog gone good.
