1. ZAM Gameplays I've seen on YouTube are running and knifing, running and sniping, running, sniping, and knifing, and camping. When I started my YouTube channel I wasn't too sure what to upload but when I watched Whitelightning's video, Bloody's videos, and indy's videos I finally knew what I wanted to upload. 2. Well, there's ZD Soft Screen Recorder, D3DGear, Fraps, Dxtory, Action!, Loilo, Sony Vegas, Bandicam, Open Broadcaster Software, FFsplit, GeForce ShadowPlay, XSplit Broadcaster + Gamecaster, CamStudio, and many others. What I recommend you do is check them out and see what you like best or get advice from your Steam friends. 3. You can choose if you want to have friends or not in your YouTube videos. I understand you are looking for suggestions but it's your YouTube channel not ours. 4. Already Steam friends with you. You can always message me if you need advice. 5. Talk in your videos. Just be brave!
