Oh boy, this is one hell of a game. I'll go ahead and get the elephant out of the room, this game COULD have been good IF they added the option to go back to levels instead of replaying the ENTIRE GAME to get each ending. All you would have to do is start at Stage 4, get two of the Stage 5 levels, and you can get all Stage 6's from there and replay the Stage 6's until you get every ending. Instead, they force you to replay the game EVERY SINGLE TIME you want a new ending. For a game where you need to get ten different endings, this is such a bad idea. The story isn't even that good either, some plot points get jumbled together due to the morality system, so the story ends up not being cohesive anyway. For example, in the Pure Dark route, the army general guy sends out Diablon to fight Shadow, which makes sense as to why you would fight him. However, I did a Pure Hero run and got the Dark ending, but there was no mention of Diablon for a while, so his appearance made no sense whatsoever. The gameplay itself isn't terrible, but the boss battles are absolutely horrid. The only boss I unironically liked was Egg Dealer, which says a lot because that boss is literally "spam A to win." Getting all of the endings didn't feel that rewarding either, since Last Story wasn't even that fun or different, it was the same map as Final Haunt and Black Comet but you need Chaos Control every two minutes, plus the final boss is terrible to play. The soundtrack isn't bad, but for Sonic standards, it's on the lower side. Other games like Unleashed, Rush, both Adventure games, and the Classic games have soundtracks that stick in your head, but this game's soundtrack didn't really have that for me, maybe it's because the gun and explosion sound effects are too overbearing. Speaking of, when you do the Hero or Dark missions, your partner will be telling you what to do at every single moment whether or not you press the hint button or not, which gets very annoying depending on the character. Some of them are fine like Sonic and Espio, but characters like Tails and Charmy can really get on my nerves at times (still love Tails though). At the very least though, the special stages don't exist and the levels are shorter, though only in the Neutral missions. The Hero and Dark missions can be very annoying at times, since a majority of them are "kill x amount of enemies" or "find x amount of collectibles" which gets really tedious very fast. Some missions can be unclear as to what to do, and for a platformer that relies on speed, these missions can really slow down gameplay and ruin that aspect. At least the game is ironically funny, with stupid lines like the iconic "fourth Chaos Emerald," "find the computer room" and my personal favourite "this is like taking candy from a baby, which is fine by me." Other than that. this game is a drag to play through and has very little going for it. Overall, I would say this game isn't really worth your time unless you want to make fun of it with your friends (though I apologize to whoever plays it).
