Thanks. The Wii-U looks more my style. So far, I just buy dedicated consoles with games built into them. I was a big fan of the NES Classic, the SNES Classic, and the Sega Genesis Mini. Thank you for the info.It largely depends on if you prefer to buy games outright or temporarily own them.
Nintendo's previous console, the Wii U, can be bought for a decent price used or refurbished. It has has 94 NES games, 51 SNES games, and 40 Turbo-Grafx-16 games, each priced between $5-$8. You keep the games and can download and delete them as many times as you want. Here's the full list: List of Virtual Console games for Wii U (North America) - Wikipedia
The Switch is more expensive than the WIi U and has a subscription service for some of their classic games. You can pay $4 per month or $20 per year for access to more than 60 NES and SNES games. You can rewind, save multiple times, and play against other people online or locally. The catch is that once your subscription ends you no longer have access to any of those games until you renew your service. The list: Nintendo Switch Online - Wikipedia
The Switch also has something called Arcade Archives which features around 200 arcade games from the 1980's and 1990's such as Donkey Kong, Frogger, Mario Bros, etc each priced at $8. Once you buy the games you keep them forever and you can save and adjust the difficulty to your liking. The full list: Arcade Archives - Wikipedia
If you want to play brand new games that have the 2D retro look and controls they're are over 100 on both systems but the Switch has the most. New ones release almost every week. 41 Best Pixel graphics games for Nintendo Switch | 50 Games Like
