It sounds dumb but my pick would be the SNES. There’s just something about 16 bit games I love.
The SNES has so many good games, like sf2. The first party games and some good arcade ports.
It also has a lot of good RPGs, like chrono trigger
The controller is really cute
Tho, the PSP is a close second. Tekken dr running at 3x resolution looks beautiful
Yes I’m a sucker for dpad centric devices. Yes i love emulation.
16 bit stuff looks amazing
PS3 is my favorite too. I love that era of gaming. I emulated some I missed out on like Asura’s Wrath, Shadows of the Damned, and Lollipop Chainsaw and they really hold up well still with the art style chosen being more cartoon than realiatic for its time. And I’ve hopped in for short sessions in Red Dead Redemption.
I actually picked up a ps3 slim and a decent handful of physical games. You can still buy digital ps3 games too on the console itself
