From Nintendo: "Explore waters and catch legendary fish in Cast n Chill on Nintendo Switch 2 and Nintendo Switch. Cast n Chill is a cozy fishing game where you explore serene lakes, rivers, and oceans. Catch rare fish, upgrade your gear, and reel in legendary catches—all with your loyal companion by your side. Have a boat buddy? Enjoy co-op, either side-by-side or with a bit of friendly competition."
We're not gamers, but if you are and can't get to the water for the real thing, the latest and greatest in graphic technology has seemingly reverted to the 90's, and is very pixel heavy, so maybe this is right up your retro alley. Maybe there will be an update or option flyfish, because we all know it's way cooler.
