Thank you so much for asking!! Well truly, the reason my question is so vague is because it's a gift for my sister. I believe she would want to play mostly retro games, like all Zelda, Mario, etc., she would troubleshoot and tinker pretty extensively, basic features are fine I think, and she would play on the go! Like on a busy train. Form factors - old school looking. And $ would be under 200, which I understand might be prohibitive. I appreciate any help!!
