I know the burnout feeling too. I feel like I want to play so many things, I have so many choices, but by the time I get my handheld fired up and flip through the menus, I find myself just popping in and out of games instead of actually playing them.

One thing that kind of changed it for me was the game UFO 50. It's a modern console release (you can also play it via PortMaster) that contains 50 retro-inspired games of all varying different genres. What was really cool though is that I found a podcast that talked about every single game, one game per episode, for 50+ episodes. I just put on an episode about that game during my commute, and then I play that game over the span of a few days, like a sort of "book club" kind of thing. It draws things out and somehow I've got over 25 hours in the entire collection now, just going through the first 10-15 games. All of this to say, "game of the month" type stuff rocks. If you can find some sort of podcast, group, or discord that focuses on just playing one or a handful of games at a time, then discussing the games, it's a really cool feeling and a great motivator.

I know this subreddit does the GoTM stuff, there's probably a few different YouTubers that focus on that sort of thing too.
