10 of the best handheld games ever

Sonic The Hedgehog Chaos (Game Gear)
Let's be honest: the Game Gear wasn't a great handheld console, and a big part of that was the lack of must-have titles. Sonic Chaos is one of the few genuinely fun games: it featured the fleet-footed rodent when he was still a bona fide gaming star and Sonic games weren't regarded as a massive joke, and was the first time we got to play as his little ginger buddy Tails.
