Rome total war videos are good, it's a hard game to master. I also like zelda speed runs. Child hood memories that make me laugh.
Sometimes I watch streams of old video games for nostalgia, at least streams are rarely cut into 50+ parts like youtube vids. I also watch streams from Celgaming, when he plays something I'm interested in or something that sounds interesting as he is quite hilarious and actually good at games. Also, I don't know why but his Brittish? accent makes everything seem funnier. In general though, I don't really like watching streams since most streamers just try too hard to be funny or are just bad at the game which I can't stand.
You're asking this on the forum of a game in which the spectatormode is considered the third faction.
