I bought a used Retroid Pocket 3 Plus recently. It's a 2-3 year old android os device that looks a lot like a PSP. The device came reset, no games.
This is not a toy. It is a project / puzzle / learning opportunity for someone interested in collecting retro games from the PS2 on back. It handles up to PS1 and PSP games really well. I've only played God of War from the PS2 on it, and it went into slow motion. I may be able to fix that within the settings. All I really wanted was a PSP, Sega Genesis, and Gameboy Advance machine. I've discovered I like some Dreamcast stuff, and I'll probably discover a few more systems. I've had a lot of fun with it after a few days of setting it up, including multiple device resets. (okay, maybe its a toy after all that work is done).
I don't play most games for more than a few minutes. I get in, get my dopamine, and switch games. I've spent the most time on Puzzle Quest, which is a match 3 game, like a million games in the IOS app store! Live and learn. It was a fun experience, and I can now play Contra, Goldeneye, Sonic, or GTA Vice City Stories any time I want.
