thinking about games, there's nothing left footage of online games in early mid00s especially not popular one

for example, minor nexon games and candybar games before 2006

because at that time, there's no usable screen recording software

hypercam(crap) and camtasia was appeard in 2005

proper 720p 60fps recorder was popularized in late 2014 after first launch of OBS (2012)
