Game Boy Advance
for anyone here thats knows about any of these which one would you own and what are the good/bad points
NDS is also a great choice too actually since it survived for a very long time so it has all the great nintendo games on it. A 3DS isn't a bad idea either even tho u want retro, it can still play all the older games that were on the nds.
Idk anything bout the gamegear.
GBA SP if anything bc of the charging and backlight features compared to a regular gba
Or get the very good Switch...
I'd suggest an NDS personally if you get one of the older versions, it has a GBA slot too. So you have the benefit of playing GBA games and NDS games, both of which has some pretty awesome titles.
I am Looking for the handheld with the best choice of games and most variety
I like look of the GBA it has alot of decent well loved games and I my go for that
