I've been enjoying the Evercade Piko Collection 3 cart recently. When new carts come out I like to try out every game and go in-depth on a least a couple games so I have a reason to come back to it later after there's a new shiny out.
So I've been playing and streaming 40 Winks (I'm about halfway through now), enjoying some Radikal Bikers, and loving to hate the hilariously bad Sword of Sodan.
