What videos to make?!

Hey guys, im about to get my new pc in a day or two and i will acctually have a good enough rig to record some games, and so i will be making a youtube gaming channel. Is thier any games that people dont make alot of content on that people would like to see content on? Like i plan on putting up some lie coms on like Tf2 because i rarely see live coms on that game and everyone just does strat videos....ay help with game suggestions would be apreciated, and if anyone ould like to donate some apare games i would be very happy!

Black Mesa, Commander Keen:The Secret Of The Oracle, Carmageddon (any of them).
