Ive been watching oxhorn recently he does narrative videos for the fallout franchise that are great and interesting

AstralSpiff and backseat streams are speedrunners that absolutely wreck games in ways no creator ever intended

Karl jobst and summoning salt are good at narrating speedruns and speedrunning history

Fondly remember the yogscast I think they still do TTT videos

If you want a really good narrator of an old game krugsmash is your man/dwarf he does great with dwarf fortress

For video game development there's horrorscoped

I swear I have the weirdest watchlist lol Ive been mainly watching youtube politics and yet I have all these too XD
