Recently the opinion that there's only three good Sonic games has become more commonplace, resulting in once highly regarded titles like Adventure 2 being bashed without regret. There's some really jank levels (Sonic's final rails level and every part of the game you play as Knuckles/Rouge) that really sour the experience, but at the end of the day the charm and soul of a masterful video game are here, and when it's good it's VERY good. I'd say it's ultimately worth a shot, at least.
