The lowest bar Sonic 4 Episode 2 had to get over was being better than Episode 1, and that bar was at the earth's core. It plays fine, but there's a lot of pace breaking annoyances throughout, and overall makes for an almost agonisingly forgettable game. I don't know who needs to be told that the Sonic 4 duology is entirely skippable and that you should just play Mania, but consider this a reminder for the five of you left.
