My recommendation is don't buy a plasma in 2025. I feel the same way about smart TVs, but you can just, like, not connect your TV to the Internet. That's what I do. It works fine.

I used to own a really high-end plasma and held off on replacing it until high-end 4K OLED screens became more affordable, but I swapped it out about seven years ago and haven't missed it.

I was playing the original Castlevania on it just the other day. Game mode, RetroUSB AVS, and an 8bitdo N30 wireless controller, and the lag is only like 10-12 ms. I can play Battletoads just fine with this setup.
