It's funny, I certainly enjoy raocow playing smw hacks, ASMT and :P :P :P are both wonderful. They're absolutely what he plays most frequently, but my favorite two series from him are An Untitled Story, which is a freeware metroidvania type of game that I highly recommend, and Super Mario World 2+, a yoshi's island hack. Side note, if you ever want a playlist, check out this video and channel. Extra credits is harder to recommend a video for. Honestly just jump in to something that seems neat and fall down the rabbit hole. They're almost always worth watching. Extra history is OK, history has never been my subject, but they do a good job nonetheless. If you like LPs, their side channel Extra Play has put out some quality content lately. Animation in games is something I've always found interesting and they explore some great games to exemplify basic principles of animation.
