"Passable" is the best word I'd use to describe this collection. You get Sonic 1 2 3&K (though with 3&K as separate titles) with save states which is nice. You also get some concept art, aaaaand…that's about it. It fulfills the "Classic Sonic games on the go" quota but it does the absolute bare minimum, and on top of that the actual quality of the games themselves are hit or miss. It's nowhere NEAR Genesis GBA levels of bad, but there are noticeable framerate and sound issues that permeate throughout all titles. It does what it needs to do and I guess that's all I can really say about it in the end.
