As time goes on I don't think another console will match in the PSP. 3DS is dead and never quite got beyond Nintendo's comfort level. Vita flopped. Switch is dying and relatively huge. Steamdeck is a better switch, but still huge. Cell phones are at best good emulators for other systems. Nothing comes close to what the PSP was.

Crazy enough the 20yr mark is coming soon.

Glad to see the site still up and maintaining! (Thanks Johnny)
