The boost games are moreso what I'd consider the opposite of "moving freely". Sure Sonic can run faster in them but SA2 Sonic running out of a charged spin-dash seems pretty fast to me. And of course SA1 Sonic can spam-dash up, down and all around the map if you so please, which makes comparing just the running speed even more arbitrary. The "free movement" system Hasimoto introduced in Unleashed apparently required turning the level paths into a bunch of walled-off tubes where you just forcibly burst in one direction no matter how you maneuver. Not to mention the plentiful level sections that remove an axis of movement entirely. I agree with Shaddy that Sonic should be restrained to about his SA2 speed in Frontiers 2, but mainly because I'm not sure if that'd be much of a nerf to begin with. The level design would just have to facilitate actual free movement! I feel like I'm beating a dead boost horse here but point is I don't think I want Hasimoto directing muh Sonic lol.
