I have some tips.
1) Cut the boring things, It is much entertaining to watch when there are only good or funny moments in the video. It makes room for more games 2. So instead of 2 games you can do 4 or something.
2) Be more enthustiastic while you record.
3) Add some music in the background.
4) Just in General: Have fun while recording and think what would I like to watch. Bcs most of the time that is what other people also want.
