Call me nostalgic, but retro games are one of my favorite ways to entertain myself, whether on a long flight or during downtime at the end of a long day. There are a few things that help me unwind, like a good old-school JRPG. I’m clearly not alone, given the breadth of retro-emulation handhelds on the market. I tend to use older Android phones for the task simply because they are powerful enough and have long-lasting batteries, and I already tend to have one or a few sitting around.
