Retro gaming brings a feeling of nostalgia for most that are into it. My video game life started off on an Atari 2600, so playing old games from my childhood is fun and a reminder of easier times. That being said NES provides a bunch of pick up and play fun games. Here is a short list of fun games to play.

Mike Tyson’s punch out Mega Man series- Mega Man 2 has the most banger soundtrack. R-Type Alpha mission RC Pro Am Ironman Ivan Stewart’s Off-road Super sprint Double Dragon Kung Fu

These should provide a bunch of different play types and genres to figure out what types of games scratch your itch.

Not sure how you feel about emulation, but take a look at FPGA systems like the MiSTer or Analog Pocket. These use hardware/chip simulation to recreate a 1:1 real hardware experience. You can also use original controllers via adapters with 0 lag, so the games feel the same too. With one of these systems you will be able to play all of those systems plus a bunch more. It’s a cool system, highly recommended.
