Honestly Forces feels incomplete, like they had to rush the game. Emerald chaos are not necessary to get a true ending (there is no such thing) or secret final boss like most of Sonic games. Classic Sonic is there for no reason like they force the studio to shoe horn in. A big plot pint point is that Eggman sends Sonic and the Avatar to the equivalent of the Shadow realm, and they escape in 20 seconds. Missing bosses, Infinite literally gets forgotten at the end (probably was killed off screen). Campaign is literally 3 hours long, 2 hours and a half if you are good. If you finish 100 % of the game they playtime go to 4 hours.

Sonic Forces.

Not good, but not bad.

It has problems, but it's not like it's a pain to play it.

It's biggest sin was not living up to the hype train.

The music is AWESOME at least. Like more then usual.
