What games should I record for my Youtube?

I will record Minecraft and Halo 4 gameplay with commentary.
Just need a few more games.
Also need an account name.

Account name are generally taken by your most commonly used online nickname in whatever games you played.
Play whatever you're best at and whatever you enjoy, when it comes to watching gaming channels people usually look for new content or gameplay that the average gamer can't or doesn't have the time to reach (pro dota, WoW arena).
