If you like dry humor, I highly recommend supergreatfriend. He's a let's player who specializes in cheesy horror games, but he's branched out quite a bit over the years. My personal favorite is his "Bully Demise" series, where he makes an ironic original character in a terrible wrestling game and imports it into other games for a goofy overarching story, though the end contains a lot of references to his other LPs that probably won't make sense to newcomers. AdumPlaze can also be pretty entertaining, but the co-hosts like to try way too hard for shock laughs, sometimes.
