/vr/ - Retro Games

GB and GB Color, I think it's no question, it has the best selection of games.
Basically what >>3090543 said, I never owned a Wonderswan but I almost got one once and I regret not buying it. And the Game Gear was my actual first handheld so I have a lot of nostalgia for it and it was admittedly pretty damn cool to own that thing back in 1994, but other than mainly Sega games (many of which are ports of arcade and genesis games), the library isn't that diverse or expansive, plus there was the problem of the battery if you wanted to actually use it as a portable device, and the fact most of them get the screen fucked over time. Mine lasted until 2004.

Non retro it's GBA

What games should I be looking out for that I can grab for cheap.
So far my list only has Tetris and Pitman/Catrap.

Every hidden gem list is like games that are known for being awesome but cost an arm and a leg. Either that or Japanese stuff I have to buy on ebay.

Any suggestions?
