If I'm recording a run, what do I all need to be on the screen? I got my recording software set up so that it's got the timer and the game itself on the screen, but do I need anything more than that? Like, I don't need a webcam or a laptop camera to record myself as I'm playing the game, right?

Sorry if this has been answered already, I'm just kinda really new to this.

Just need game footage that's all

You need to ask the game community to be sure. Some games require things like input displays or fps displays. Some require game audio with no custom music. Some require a timer in the video. 80-90% of the time, just the video ought to be enough but there are no global rules for stuff like this.
