I usually watch NODE's (which consist of the guys from freddiew and Corridor Digital) Lan Party episodes, as well as Markiplier's and Cr1tikal's (I think his username on YouTube is penguinz0 or something) Let's Plays. Markiplier does mostly horror games, while NODE does games of various kinds. While those two do their comments at the same time they play, I hear Cr1tikal does his commentary after he records his gaming session.
