Age of Empire 2 gameplay, Ceasar campaign

Hello friends, i created this video to show the gameplay for Age of Empire 2, and the campaign of Ceasar. But this is a test video because i have some problems with OBS software and the mic, those 2 doesn't seem to work good with each other. Everytime i record a video and start to talk, it goes wrong.

For unknown reasons the sound of my mic is suddenly gone and i have no idea how or what, there for i tried different settings of OBS, from different videos i saw on Youtube, and still the same problem occurs. So now i tried a different program called Audicity, to record my voice only, but i did not manage yet to create a video. That will be next, but for now enjoy the video. Cheers
