The main problem with Sonic Forces was that the levels were way too short and linear compared to other Sonic games (and other platformers in general, the game really was a disappointment, which partly explains the extremely positive reception Frontiers is getting). A 4 hour completion time for a platformer if you're good at it would be totally fine, the problem is that Sonic Forces set the bar so low that everyone can do that first try without any practice. Sonic games usually have alternate paths and tricky sections you need to practice to do quickly, so you might beat the game in 3 hours while finding all the collectibles, but only after practicing the run for much longer than that.
