the current android socs run up to and including ps/dreamcast/wii quite normally
a steam deck can also handle switch ( only SD socs partly on android ) and wiiu ( is not yet available for android ) and also partly with ps3
for xbox360 and higher or ps4 you can currently make do with gamepass/playstation+ (streaming from console or cloud)
and for anything that requires a little more power or compatibility, you can use moonlight (or similar) to stream from your PC if it’s powerful enough.
and for those wondering, yes I personally have the games that I run on it (yes that will not be the case for everyone, yes) but what makes a similar device so attractive is the accumulation.
I don’t have to keep getting my gc, wii, wiiu, ps2 … from the attic, connected with horrible controllers sometimes by today’s standards
just nice on 1 thing that is easy to take with you
because of this specific device, I think aya neo releases beautiful things, albeit usually overpriced, but not really this imo
especially the smaller screen (or OLED here) compared to Ayn’s direct competitor is a downside.
